When Motion Commands Are Used
When motion commands are used, the meanings of the speed-related parameters differ
according to the Speed Reference Selection (bit 13 of OWC001).
The following table shows some examples of the parameter settings.
Table 11.14 Parameter Setting Examples
∗ Select Enabled (= 1) in bit 9 (override enabled selection) of motion fixed
parameter No. 17.
The rated rotation and feedback pulse per motor rotation are automatically transmitted to the MP940
connected to the SGDH SERVOPACK when the power is turned ON.
The pulse counting method is A/B mode (fixed at 4 multiplication).

• Description
Pulse counting method = A/B mode (fixed at 4 multiplication)
Rated rotation = 3000 r/min.
Feedback pulse = 2048 P/R
Rated speed = 3,000 r/min
= 3000 2048 4
= 2575000 ppm
