Explanation of function and operation
1. 16-bit operation (PLSR)
Pulses are output from output (Y) by the specified number with acceleration/deceleration to the
maximum frequency over the time (ms).
: Maximum frequency (Hz)
Allowable setting range: 10 to 32767 (Hz)
: Total number of output pulses (PLS)
Allowable setting range: 1 to 32767 (PLS)
: Acceleration/deceleration time (ms)
Allowable setting range: 50 to 5000 (ms)
: Pulse output number
Allowable setting range: Y000, Y001
