VFD-L-I Series
4-32 Revision July 2009, SW V1.1
Group 5: Multi-step speeds and PLC (Process Logic Control) parameters
05-00 1st Step Speed Frequency Unit: 0.01
05-01 2nd Step Speed Frequency Unit: 0.01
05-02 3rd Step Speed Frequency Unit: 0.01
Settings 0.00 to 400.00 Hz Factory Setting: 0.00
The Multi-Function Input Terminal (refer to Pr.04-04) is used to select one of the AC drive
Multi-Step speeds. The speeds (frequencies) are determined by Pr.05-00 to 05-02 shown
above. It can use with Pr.05-03~Pr.05-08 for PLC operation.
05-03 PLC Mode
Factory Setting: 0
Settings 0 Disable PLC operation
1 Stop after executing one program cycle
2 Continuously execute program cycles
3 Execute one program cycle step by step
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.05-03 = 1): Execute one cycle of the PLC program. Its relative parameter settings
are:
1. Pr.05-00 to 05-02: 1st to 3rd step speed (sets the frequency of each step speed).
2. Pr.04-04: Multi-Function Input Terminals (set one multi-function terminal as 16- Run PLC
Program).
3. Pr.03-03: Multi-Function Output Terminals (set a Multi-Function Terminal as 10- PLC Program
Running, 11- PLC Program Step Completed or 12- PLC Program Completed).
4. Pr.05-03: PLC mode.
5. Pr.05-04: Direction of operation for Master Frequency and1st to 3rd step speed.
6. Pr.05-05 to 05-08: operation time setting of Master Frequency and1st to 3rd step speed.
