Observe "Use as directed" on page 10.
The monitoring contacts (KSO1/2) for each amplifier with an -AS- option must be
looped into the control circuit. This is vital, so that a malfunction of the internal safety
relay or a cable break can be recognized.
If the -AS- option is automatically activated by a control system (KSI1/2), then make
sure that the output of the control is monitored for possible malfunction. This can be
used to prevent a faulty output from activating the -AS- option while the motor is run-
ning.
It is vital to keep to the following functional sequence when the -AS- option is used:
1. Brake the drive in a controlled manner (speed setpoint = 0V)
2. When speed = 0 rpm, disable the servo amplifier (enable = 0V)
3. If there is a suspended load, apply an additional mechanical block to the drive
4. Activate the -AS- option
Stop all drives, with setpoint 0V, disable drives,
mechanically block any suspended loads
Activate the -AS- option.
Open protective screens (but do not enter hazardous area)
Pull off the X10 connector from an amplifier: the mains contactor must drop out
Reconnect X10. Switch on mains contactor again.
Repeat steps 4 and 5 for each individual servo amplifier.
