VFD-M Series

5-36

Continuously execute program cycles step by step (separated by

“STOP”)

 This M drive can be programmed to execute a sequence of operations named “PLC

mode”. 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. This parameter selects the PLC operation mode for the drive. Please

review the following examples:

Example 1 (Pr.78 =01):

Execute one cycle of the PLC program. Its relative parameter settings

are:

1 Pr.17 to Pr.23:

1st to 7th step speed (sets the frequency for each step speed)

2 Pr.38 to Pr.42:

Multi-Function Input Terminals (program one multi-function terminal for PLC

auto-operation (16)).

3 Pr.45 to Pr.46:

Multi-Function Output Terminals : program a Multi-Function Output Terminal

for PLC operation indication (09), one cycle in PLC auto mode (10) or PLC operation

fulfillment attainment (11).

4 Pr.78:

PLC mode.

5 Pr.79:

Direction of operation for Master Frequency and 1st to 7th step speeds.

6 Pr.81 to Pr.87:

operation time setting of Master Frequency and 1st to 7th step speeds.
