1) To ensure that the Σ-series Servo System operates properly, set the type of the encoder
to be used and the number of encoder pulses per revolution in the following user
constants:
Encoder Type Selection
Cn-01 Bit E
Set the encoder type according to the servomotor type to be used.
After changing the memory switch setting, turn the power OFF, then ON.
Motor Type
SGM-jjj31j Incremental encoder: 2048 pulses per revolution
SGMP-jjj31j
Absolute encoder: 1024 pulses per revolution
SGM-jjjW1j
SGMP-jjjW1j
PULSNO
Number of
Cn-11 Encoder Pulses
Set the number of encoder pulses according to the servomotor type to be used. If this
user constant is set incorrectly, system operation cannot be guaranteed.
After changing the memory switch setting, turn the power OFF, then ON.
