Observe the prescribed use of the restart lock -AS- (ð p. 10)
The monitoring contacts (KSO1/2) for each amplifier 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 restart lock -AS- 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 restart lock -AS- while the
motor is running.
Keep to the following functional sequence when the restart lock -AS- 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, block the drive mechanically
4.
Activate the restart lock -AS-
Stop all drives, with setpoint 0V, disable drives,
mechanically block any suspended loads
Activate the restart lock -AS-.
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.
