9 Important Circuit Information
9.2 Infeed modules
Terminals AS1,
AS2
Terminal X131
Terminal X141
Terminals 2U1,
2V1, 2W1
Terminals P500,
M500
9-254
Signaling contact, start inhibit DC link controller
(not available for NE modules 5, 10, 28 kW)
Reference potential
05.01
When coupled to a numerical control, X131 must be connected to the NC reference
potential. This cable must be routed in parallel with the speed setpoint
cable.
Cross–section = 10 mm�!
For a digital drive group with 840D/810D/840C, keep terminal X131 open circuit.
Electronics voltage
� Term. 7: P24; +20.4 ÷ 28.8 V / 50 mA
� Term. 45: P15; +15 V /10 mA
� Term. 44: N15; –15 V/10 mA
� Term. 10: N24; –20.4 ÷ 28.8 V / 50 mA
� Term. 15: M; 0 V
It is not permissible that terminal 15 is connected to PE (ground loop)
It is not permissible to connect terminal 15 to terminal 19 (otherwise a short–circuit
via the reactor would occur – terminal 15 is internally connected to X131).
Terminals to allow the internal electronics power supply to be separately connected,
e.g. through fused terminals (refer to the circuit example in Chapter
9.3.1).
In this case, jumpers 1U1–2U1, 1V1–2V1, 1W1–2W1 must be removed (opened).
Notice
Additional information is provided under Chapter 9.3 Monitoring module and
Chapter 9.13 Observe the six–conductor connection!
The internal power supply connection at DC link P600/M600.
e.g. for power failure concepts.
Notice
With this operating mode, terminals 2U1, 2V1, 2W1 of the power supply must
be supplied with the line supply voltage between the I/R module and line reactor.
For a six conductor connection (refer to Chapter 9.13) it is not permissible to
establish a connection between P500/M500 and the DC link P600/M600.
Otherwise, the power supply will be destroyed!
