(11) Command position number (PC1 to PC512)
The command position number is read as a binary code.
The size of the command position number varies, as follows, according to the operation mode:
•
Position number specification mode PC1 to PC32 64 points
•
Command specification mode, positioner operation PC1 to PC256 512 points
•
Command specification mode, simple direct operation PC1 to PC32768
The controller unit reads the PC signal as a binary command position number at the “0” (OFF) “1”
(ON) edge of the CSTR signal.
(12) Completed position number (PM1 to PM256)
These signals are effective in the position number specification mode and command specification
mode, simple direct operation.
The completed position number is output as a binary code.
Immediately after the power is turned on or while the actuator is moving, all signals from PM1 to
PM256 are turned “0” (OFF). Although all of these signals turn “0” (OFF) when the servo turns OFF
or an emergency stop is actuated, they will turn “1” (ON) again if the actuator is inside the positioning
band (INP) relative to the target position when the servo is turned ON again. If the positioning band
(INP) is exceeded, the signals will remain “0” (OFF).
These signals also turn “1” (ON) upon completion of push-motion operation and when the actuator
has missed the work in push-motion operation.
(13) Zone (PZONE, ZONE1, ZONE2)
These signals turn “1” (ON) when the current actuator position is inside the specified zones. *1
Each zone is set in the position table or using user parameters.

completed, the signals will remain effective even while the servo is OFF.
