Self-Diagnostics

The drive can use Self-Diagnositcs to find the operation of the serial communications interface circuit. Self-
Diagnostics connects the transmission terminal to the reception terminal on the control circuit. It then transmits
the data sent by the drive and makes sure that the drive can communicate correctly.
Use this procedure to do Self-Diagnostics:
1.
Energize the drive.
2.
Set H1-06 = 67 [Terminal S6 Function Select = Communications test mode].
3.
De-energize the drive.
4.
Connect a jumper between control circuit terminals S6 and SN.
5.
Energize the drive.
6.
When normal, the keypad will show PASS [MEMOBUS/Modbus Communications Test Mode Normal].
When there is an error, the keypad will show CE [MEMOBUS/Modbus Communications Error].
7.
De-energize the drive.
8.
Disconnect the wire jumper between terminals S6 and SN. Set terminal S6 to its initial function.
Self-Diagnostics is complete and the drive returns to its usual function.

When the drive receives the Enter command from the
master
Checks the upper and lower limits and considers the
related parameter settings.
Will not change related parameter settings. You must
change the parameters manually.
Accepts and responds as usual to correct setting data if the
data contains parameter setting errors. The drive discards
the disabled setting data, but will not return an error
message.

When you change the parameter settings
Checks the upper and lower limit of the changed
parameter only.
Automatically changes the default settings for the related
parameters.
If there is a setting error in a parameter, the drive
responds with a fault. The drive discards the data that was
sent.
