†If StepNLoop is enabled, the [HSPD range] values needs to be transposed from PPS (pulse/sec) to EPS (encoder
counts/sec) using the following formula:
EPS = PPS / Step-N-Loop Ratio
Acceleration/Deceleration Range
The allowable acceleration/deceleration values depend on the LS and HS settings.
The minimum acceleration/deceleration setting for a given high speed and low speed is shown below.
Max ACC = ((HS – LS) / δ) × 1000 [ms]
Note: The ACC parameter will be automatically adjusted if the value exceeds the allowable range.
Examples:
a) If HSPD = 20,000 pps, LSPD = 10,000 pps:
a. Min acceleration allowable: 1 ms
b. Max acceleration allowable:
((20,000 – 10000) / 775) x 1,000 ms = 12,903 ms (12.9 sec)
b) If HSPD = 900,000 pps, LSPD = 9,000 pps:
a. Min acceleration allowable: 1 ms
b. Max acceleration allowable:
((900,000 – 9,000) / 38,400) x 1000 ms = 23,203 ms (23.3 sec)
