Fault detection when setting more than one parameter
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.
If there is a setting error in a parameter, the drive responds
with a fault. The drive discards the data that was sent.
◆
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 Selection = Communications Test Mode]
.
3.
De-energize the drive.
4.
Connect a jumper between control circuit terminals S6 and SN.
Figure 6.12 Self-Diagnostics Jumper Terminals
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.
