NOTE

When a Base-Block signal is received, the AC drive will stop all output and the motor will free run. When base block control is deactivated, the AC drive will start its speed search function and synchronize with the motor speed, and then accelerate to Master Frequency.

d15, d16 Increase/Decrease Master Frequency:

Parameter values d15, d16 program the Multi-Function Input Terminals: M1 (Pr.4-04), M2 (Pr.4-05), M3 (Pr.4-06), M4 (Pr.4-07) or M5 (Pr.4-08) to incrementally increase/ decrease the Master Frequency each time an input is received.

Mx "Close": Freq. will increase by one unit.

Mx "Close":Freq. will decrease by one unit.

GND

d17, d18 PLC Function Control:

Parameter value d17 programs Multi-Function Input Terminal: M1 (Pr.4-04), M2 (Pr.4-05), M3 (Pr.4- 06), M4 (Pr.4-07) or M5 (Pr.4-08) to enable the AC drive internal PLC program. Parameter value d18 programs an input terminal to pause the PLC program.
