Mode of operation

Parameters critical for operation are monitored in the monitoring module, for
example:
S
DC link voltage
S
Controller power supply (15 V)
S
5 V voltage level
If these parameters are in the permissible operating range, then the internal
prerequisites are provided for the "equipment ready" signal. The group of modu-
les is enabled at the monitoring module as soon as the external enable signals
have been made available via terminals 63 (pulse enable) and 64 (drive ena-
ble). The sum signal controls the "ready" relay and can be taken, floating, via
terminals 72/73.2 and 73.1/74. The load capability of the contacts is 250 V AC/1
A or 30 V DC/1 A.
The signal statuses of the monitoring circuits are displayed using LEDs on the
front panel of the monitoring module
