Group 5: Multi-step Speed, Process Logic Control Parameters
5 - 00 1st Step Speed Frequency
5 - 01 2nd Step Speed Frequency
5 - 02 3rd Step Speed Frequency
Settings
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.
5 – 03

PLC Mode

Settings
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
2. Pr.4-04 to 4-06: Multi-Function Input Terminals set one multi-function terminal as d16-
PLC auto-operation
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
6. Pr.5-05 to 5-08: operation time setting of Master Frequency and 1
