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.
5-07 PLC 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 1
st
speed to 7
th
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: 1
st
to 7
th
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 and1
st
to 7
th
step speed.
6. Pr.5-09 to 5-16: operation time setting of Master Frequency and1st to 7th step speed.
