7 Application Instructions API 50-99 When M1257 is Off, the acceleration/deceleration slope is a straight-line curve, as shown below. Frequency F F0 Start frequency When M1257 is On, the acceleration/deceleration slope is an S curve, as shown below. 1 ~ 5,000ms 1 ~ 5,000ms F F S 1 S 1 F0 F0 Time Time S 3 S 3 S 3 S 3 3. The acceleration/deceleration of EH/EH2/SV/EH3/SV2 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 PLSR. 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.
