3.

The acceleration/deceleration of EH/EH2/SV series MPU is based on the number of pulses. If the output cannot

reach the maximum acceleration frequency within the acceleration/deceleration time offered, the instruction will

automatically adjust the acceleration/deceleration time and the maximum frequency.

4.

The operands have to be set before the execution of the instruction.

5.

All acceleration/deceleration instructions are included with the brake function. The brake function will be

enabled when PLC is performing acceleration and the switch contact is suddenly Off. The deceleration will

operate at the slope of the acceleration.
