The Multi-Function Input Terminals (refer to Pr.4-04 to 4-08) are used to select one of the AC

drive Multi-Step speeds. The speeds (frequencies) are determined by Pr.5-00 to 5-06 shown

above.

5-07PLC Mode

		Factory Setting: d0
Settings	d0	Disable PLC operation
	d1	Execute one program cycle
	d2	Continuously execute program cycles
	d3	Execute one program cycle step by step
	d4	Continuously execute program cycles step by step
	d5	Disable PLC operation, but can set direction of 1st speed to 7th
		speed

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.

When this parameter is set to d5 and it is running by external multi-speed, the high priority of

the operation direction is Pr. 5-08.

Example 1 (Pr.5-07 = d1): Execute one cycle of the PLC program. Its relative parameter settings are:

1.Pr.5-00 to 5-06: 1st to 7th step speed (sets the frequency of each step speed).

2.Pr.4-04 to 4-08: Multi-Function Input Terminals (set one multi-function terminal as d17- PLC auto-operation).

3.Pr.3-05 to 3-06: Multi-Function Output Terminals (set a Multi-Function Terminal as d10-PLC operation indication, d11-one cycle in PLC auto mode or d12-PLC operation fulfillment attainment).

4.Pr.5-07: PLC mode.

5.Pr.5-08: Direction of operation for Master Frequency and1st to 7th step speed.

6.Pr.5-09 to 5-16: operation time setting of Master Frequency and1st to 7th step speed.
