3.3.3 Setting the Number of Encoder Pulses
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 parameters:
Cn-01 Bit E
Encoder Type Selection Factory
Setting: 0
For Speed/Torque Control
and Position Control
Set the encoder type according to the servomotor type to be used.
After changing the memory switch setting, turn the power OFF, then ON.

Number of Encoder Pulses Per Revolution Preset Value
2 Incremental encoder: 8192 pulses per revolution
3 Incremental encoder: 2048 pulses per revolution 0
6 Incremental encoder: 4096 pulses per revolution

Position Control
Set the number of encoder pulses according to the servomotor type to be used. If this
parameter is set incorrectly, system operation cannot be guaranteed.
After changing the memory switch setting, turn the power OFF, then ON.
