Specifications and
Operation
When the start input (0.00) goes ON, this example program outputs 600,000
pulses from pulse output 0 and turns the motor.

Remarks
• Absolute pulses can be specified when the origin position has been deter-
mined.
• If a target frequency that cannot be reached has been set, the target fre-
quency will be reduced automatically, i.e., triangular control will be per-
formed. In some cases where the acceleration rate is substantially greater
than the deceleration rate, the operation won't be true triangular control.
The motor will be operated at a constant speed for a short time between
the acceleration and deceleration.
