Turning the Power ON and OFF, and Booting the System FP2 positioning Unit
5-6
5.3.2 Procedure for Turning OFF the Power
Procedure:
1. Check to make sure the rotation of the motor has stopped, and then turn OFF the power supply for the
motor driver.
2. Turn OFF the power supply for the PLC.
3. Turn OFF the power supplies for input and output devices connected to the PLC (including the power
supply for the line driver output or open collector output).
Precautions when rebooting the system
The flags of the operation memory are initialized simply by initializing the CPU, but the flags of the
shared memory for the positioning unit are retained.
If the positioning unit is operated with data still in the shared memory, operation may be carried out
based on any set values which have been retained, in some cases. The flags of the shared memory can
be cleared when the power supply is turned OFF.
