5.1 I/O Signal List

The following device No.s are those for station 1.

For stations 2 and later, the device No.s are different. (For the device No. correspondence list, refer to the master unit manual.)

5.1.1 Output signals (master unit →

inverter (FR-E5NC))

 

 

 

 

 

The output signals from the master unit are indicated. (Input signals to inverter)

Description

 

 

No.

 

 

 

 

 

 

 

 

RY0

Forward rotation command

OFF : Stop command

 

 

ON

: Forward rotation start (Note 1)

 

 

 

 

 

 

RY1

Reserve rotation command

OFF : Stop command

 

 

ON

: Reserve rotation start (Note 1)

 

 

 

 

 

 

RY2

RH terminal function

 

 

 

 

(high speed)

 

 

 

 

 

Functions assigned to RH/RM/RL are selected.

 

 

RY3

RM terminal function

 

 

In the factory setting, multi-speed selection can be made by the combination of RH, RM

 

 

(middle speed)

 

 

 

and RL. (Note 2)

 

 

RY4

RL terminal function

 

 

 

 

 

 

(low speed)

 

 

 

 

 

 

 

 

 

RY5

 

 

 

 

 

RY6

Reserved (Note 5)

Reserved for the system.

 

 

RY7

 

 

 

 

 

 

 

RY8

 

 

 

 

 

RY9

Output halt (MRS)

When the MRS signal switches on, the inverter output stops.

 

Note: 1. Switching on RY0 and RY1 at the same time gives a stop command.

2.With Pr. 180 to Pr. 183 (input terminal function selection), you can set the input signals of device No.s RY2 to RY8. For full information, refer to the inverter manual.
