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.
