This parameter can be set during operation.
The Multi-Function Input Terminals (refer to Pr.4-04 to 4-06) are used to select one of
the AC drive Multi-Step speeds. The speeds (frequencies) are determined by Pr.5-00
to 5-02 shown above.

Factory Setting: d 0
Settings d 0 Disable PLC operation
d 1 Execute one program cycle
d 2 Continuously execute program cycles
d 3 Execute one program cycle step by step
d 4 Continuously execute program cycles step by step
This parameter selects the mode of PLC operation for the AC drive. The PLC program
can be used in lieu of any External Controls, Relays or Switches. The AC drive will
change speeds and directions according to the user’s desired programming.
Example 1 (Pr.5-03 = d1): Execute one cycle of the PLC program. Its relative parameter
settings are:
1. Pr.5-00 to 5-02: 1
st

step speed
sets the frequency of each step speed
2. Pr.4-04 to 4-06: Multi-Function Input Terminals
set one multi-function terminal as d16-

.
3. Pr.3-03: Multi-Function Output (set the relay as d10-PLC operation indication, d11-one
cycle in PLC auto mode or d12-PLC operation fulfillment attainment).
4. Pr.5-03: PLC mode.
5. Pr.5-04: Direction of operation for Master Frequency and 1

step speed.
6. Pr.5-05 to 5-08: operation time setting of Master Frequency and 1
