2 LED red – 5 V voltage level faulted
3 LED green –Ext. enable signal not available (terminal 63 and/or 64 missing) 4 LED yellow – DC link charged
5 LED red – Line supply fault (single or multi–phase line supply failure at terminals U1, V1, W1)1)
– No commutating reactor, incorrectly installed or incorrectly selected
– Fault level of the line supply or transformer too low 6 LED red – DC link overvoltage
Possible causes: Regenerative feedback off, setting–up operation, line supply fault, for UE, pulsed resistor not operational or too small, line supply voltage too high, dynamic overload, line supply filter installed between the I/R and commutating reactor

1 LED red – Electronics power supply 15 V faulted
Effects:
1 LED red bright: Pulses are deleted for the complete drive group 2 LED red bright: Pulses are deleted for the complete drive group 4 LED yellow dark: Pulses are deleted for the complete drive group
5 LED red bright: Only the I/O module pulses are deleted (regenerative feed back no longer possible. Axes initially continue to run, ready relay drops–out)
6 LED red bright: Pulses are deleted for the complete drive group
1) Line supply fault recognition time, approx. 30 ms
Line supply fault is recognized when the three–phase voltage is < 280 V.
For a single–phase power failure, the drive axis pulses are deleted after approx. 1 min

Terminals and relay functions
S X111 Ready relay
– terminals 72 – 73.1 NO contacts closed for “ready” – terminals 73.2 – 74 NC contacts open for “ready” Switch S1.2 OFF, the relay pulls–in, if:
– internal main contactor CLOSED (terminals NS1 – NS2 connected, terminal 48 energized)
– terminal 63, 64 = ON
– it is not permissible that a fault is present
(this is also true for FD 611A Standard, 611D drives or MCU)
– FD with standard interface or resolver for the “ready” setting must be enabled (terminals 663, 65)
– NCU must have run–up (SINUMERIK 840D, SINUMERIK 810D) – the MCU must have run–up
Switch S1.2 ON, relay pulls–in, if:
– internal main contactor CLOSED (terminal NS1 – NS2 connected, terminal 48 energized)
– it is not permissible that a fault is present
(this is also true for FD 611A Standard, or 611D drives or MCU)
– FD with standard interface or resolver for the “ready” setting must be enabled (terminals 663, 65)
– NCU must have run–up (SINUMERIK 840D, SINUMERIK 810D) – the MCU must have run–up
S X121 I2t pre–alarm and motor overtemperture
Terminals 5.1 – 5.2 NO contacts open for “no fault” Terminals 5.1 – 5.3 NC contacts closed for “no fault“ This relay switches, if:
– at the I/R ––> the heatsink temperature monitoring responds – at FD 611D ––> the motor temperature monitoring responds
––> heatsink temperature monitoring responds – at FD 611A user–friendly
––> motor–temperature monitoring responds (for resolvers: this is not saved, no shutdown!!) ––> heatsink temperature monitoring responds ––> I2t pre–alarm responds (this is not saved)
– at FD611A Standard
––> motor–temperature monitoring responds ––> heatsink temperature monitoring responds ––> I2t temperature monitoring responds
S X171 terminals NS1 – NS2
(coil circuit of the internal line supply and pre–charging contactor)
– is used to provide electrical isolation from the line supply (signaling contact, terminals 111 – 213 must be interrogated) – may only be switched when terminal 48 is open–circuit (without any restrictions from
NE
S Terminal 48 Start
– has the highest priority – sequence:
pre–charging ON – interrogate VDC link 300V and VDC link √2S Vsupply
– 50 V. If yes, then
500 ms pre–charging contactor OPEN, interrogate whether actually OPEN, main contactor CLOSE
1 s internal enable signal (for I/R and module group) – is saved during pre–charging
S Terminal 63 Pulse enable
– has the highest priority for enabling the pulses for all of the modules – acts instantaneously
S Terminal 64 Drive enable
– acts instantaneously on all modules
– when the signal is withdrawn, nset is set to 0 for all drives, and
– For MSD / IM 611A, after a selectable speed has fallen below, the pulses are cancelled. The drive is braked along a ramp. – For VSA 611A, all of the controllers and pulses are inhibited after a selected time has expired (setting when supplied: 240 ms). The drive is braked along the current limit.
– For 611D drives, the pulses are deleted after a selectable speed has been fallen below or after a selectable time has expired. The drive is braked at the selected limit! (for spindles, the ramp can only be achieved along the regenerative limit [kW]!)
S Terminal 112 open–circuit Setting–up operation
– The VDC link control is inhibited
– Regenerative feedback is not possible, i.e. when braking, VDC linkcan be > 600 V !
– This function can be interrogated using the start inhibit signal, terminals AS1 – AS2.
!
CautionInduction motors can reach high speeds even at low VDC link!S Terminals AS1 – AS2 Start inhibit signal
– Terminals AS1 – AS2 closed means “start inhibit is effective” (i.e. terminal 48 = open–circuit, setting–up operation)
S Terminals 111, 113, 213 Signaling contacts, internal line contactor
– Terminals 111 – 113 NO contacts
– Terminals 111 – 213 NC contacts (for I/R 16 kW and UE 10 kW, only from
NE
S Terminal 19 FR–
– Reference ground, enable voltage
– Floating (connected with the general reference ground terminal 15 via10 kΩ) – Terminal 19 may not be connected to terminal 15
(connect to PE rail, or to X131 )
S Terminal 9 FR+
– Enable voltage : +24 V
– Maximum load capacity of the power supply (power supply): 500 mA (corr. to 8 EP;1 optocoupler input required 12 mA, for UE = 5 kW ––> 1A)
S X 141 Electronic voltages – Term. 7 P24 +20.4 to 28.8 V / 50 mA – Term. 45 P15 +15 V / 10 mA – Term. 44 N15 –15 V / 10 mA – Term. 10 N24 –20.4 to –28.8 V / 50 mA – Term. 15 M 0 V
– Terminal 15 may not be connected to PE (ground loop) – Terminal 15 may not be connected to terminal 19
(short–circuit via reactor, which internally connects terminal 15 to X131)
S Terminals L1 – L2 for 80 kW and 120 kW I/R
– Is used to supply the coil circuit of the internal line contactor – directly supplied with 2–ph. 400 V AC at the line supply (not between I/R and reactor)
– Fuse: IN 4 A, version gL
S Fan connection for 80 and 120 kW I/R
– 3–ph. 360 to 510 V AC, 45 – 65 Hz directly from the line supply (not between I/R and reactor)
– Observe the direction of rotation!
– Fuse: IN 1.5 A (motor protection circuit–breaker)
S 6–wire connection
with additional power supply connection at the DC link:
– For this mode, terminals 2U1, 2V1 and 2W1 of the power supply
must be supplied with the line supply voltage between the series reactor and
I/R, as otherwise the power supply will be destroyed. The also applies to the montioring modules!
Note
This is guaranteed by the jumpers inserted in the factory at connector X181.
S Monitoring module with connection to the line supply and additional power supply connection at the DC link :
– For this mode, terminals 2U1, 2V1 and 2W1 of the power supply
must be supplied with the line supply voltage between the series reactor and
NE
The overvoltage limiting module must be checked if a line supply fault isdisplayed or the yellow LED is dark. Procedure:
1. Power–down the unit so that it is in a no–voltage condition
2. Remove the overvoltage limiting module and insert connector X181 on the NE module. If the NE module functions, then the overvoltage limiting module is defective and must be replaced. Otherwise, check the line supply and if necessary check the NE module/group.
Note
In this way, continued operation is possible, without overvoltage protection.
3. Insert the overvoltage limiting module 566018.9415.00 up to its end stop, and insert connector X181 on the overvoltage limiting module.
Note
Operation without overvoltage limiting module is not in conformance with UL!
