Operation
Note 1: Turn on the main circuit power after the control power has been turned on or at the same time
when the control power is turned on.
Note 2: Turn on the FOT and ROT signals 10 [ms] or more before the SON signal is turned on.
Note 3: When the return-to-origin has been completed, the INP signal turns on. So, turn off the ORG signal
after the INP signal has turned on.
Note 4: Turn on the PEN signal 10 [ms] or more before the position command is input.

Note 1: Turn on the main circuit power after the control power has been turned on or at the same time
when the control power is turned on.
Note 2: Turn on the FOT and ROT signals 10 [ms] or more before the SON signal is turned on.
Note 3: When the return-to-origin has been completed, the INP signal turns on. So, turn off the ORG signal
after the INP signal has turned on.
Note 4: Turn on the PEN signal 10 [ms] or more before the position command is input.
