Using the Panel Operator
1. Select the parameter Fn012.
2. Press the DATA/SHIFT Key for a minimum of one second to display the SERVO-
PACK’s Software version.
3. Press the MODE/SET Key to display the encoder software version.
4. Press the DATA/SHIFT Key for a minimum of one second to return to the parameter
number display.
6.2.8 Zero-point Search Mode
The zero-point search mode is designed to position the zero-point pulse position of the
encoder and to clamp at the position. This mode is used when the motor shaft needs to be
aligned to the machine. Execute the zero-point search without connecting the couplings.
The speed for executing the zero-point search is 60 min
-1
.
The following conditions must be met to perform the zero-point search operation.
1. If the Servo-ON input signal (/S-ON) is ON, turn it OFF.
2. Release the Servo-ON signal mask if parameter Pn50A.1 is set to 7 and the Servo has been set to
always be ON.
MODE/SET DATE/
• Forward run prohibited (P-OT) and reverse run prohibited (N-OT) signals are not effective during
zero-point search mode operations using parameter Fn003.
