Changing RY19 Multi-Function I/O Allocation

The drive’s multi-function I/O layout will change as shown below when RY19 is switched on or off.

Parameter Name RY19: OFF (Default) RY19: ON

H1-01 Multi-function input 1 24: External fault 3: Multi-step speed reference 1

H1-02 Multi-function input 2 14: Fault reset 4: Multi-step speed reference 2

H1-03 Multi-function input 3 3: Multi-step speed reference 1 5: Multi-step speed reference 3

H1-04 Multi-function input 4 4: Multi-step speed reference 2 6: Jog command

H1-05 Multi-function input 5 6: Jog command 1A: Accel/decel time selection 2

H1-06 Multi-function input 6 8: Baseblock command 8: Baseblock command

H2-01 Multi-function output 1 0: Running 0: Running

H2-02 Multi-function output 2 1: Zero speed 5: Frequency detection 2

H2-03 Multi-function output 3 2: Frequency agreement E: Fault

H3-05 Multi-func analog input 0: Auxiliary frequency reference 1F: Analog input is not used.

L4-01 Freq detection level 0.00Hz 6.00Hz

Remote Registers

(From PLC to Inverter)

Remote Register Name Description

Monitor code

Sets the monitor code. While the monitor execution request flag (RYC)

is ON after setting the code, the monitored value is stored in RW

While RW

is being updated, the monitoring signal (RXC) is turned

ON.

Setting

frequency

Sets the operation frequency. If the RYD flag is turned ON now, this

data sent to the inverter is assigned as the master speed frequency.

Turning ON the RYE flag writes in the setting to frequency reference 1

and stores the data in EEPROM

. However, the unit of the setting

depends on the setting of o1-03 (frequency reference setting/display

unit selection).

Command code

Sets the command code to execute parameter read/write, fault history,

or error reset, etc. If the command code execution request flag (RYF)

is turned ON, the inverter processes the corresponding command code,

and the command code execution completion flag (RXF) is turned ON

after the command is carried out.

Write data

Assigns the data when necessary for the command code.

Turn ON the command code execution request flag (RYF) after setting

the command code and write-in data.

* The EEPROM can be written to 100,000 times. Refrain from writing to EEPROM excessively.
