Technical data
Ready signal;
Output referred to 24 V electronics ground
Current carrying capacity: 100 mA (short-circuit proof)
Meaning:
The terminal has +24 V, if the electronics power supply is
in the specified range.
Brief voltage pulses of the 24 V supply outside of the
specified voltage range are displayed via the RDY signal
(not storing). The function of the drive train of the S120M
system is not affected by this.
If the supply voltage is permanently outside of the permit‐
ted range or if the supply voltage is exceeded by an im‐
permissible amount, the drive train of the S120M system is
shut down in a controlled way. The RDY signal displays
the fault during shutdown.
Notification: DC link voltage is present at the distributed
line
Output referred to 24 V electronics ground
Current-carrying capacity: 100 mA (short-circuit proof)
Meaning:
The terminal has 0 V, if the DC link voltage is > 50 V.
Note:
Hazardous DC link voltages may be present at any time
regardless of the state of the system.
Alarm signal: AM600 overtemperature
Meaning:
Normally, 24 V is available at this terminal, and for an
overtemperature condition, 0 V.
