When you change the parameter settings
Upper and lower limit check
Checks the upper and lower limits and considers the
related parameter settings. Checks the upper and lower limit of the changed
parameter only.
Default setting of related parameters
Will not change related parameter settings. You must
change the parameters manually. Automatically changes the default settings for the related
parameters.
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 Select = 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.

Communications Data Table
The communication data types are command data, monitor data, and broadcast message. Command Data on page
218 , Monitor Data on page 220 , and Broadcast Messages on page 231 show the communications data.
Refer to the Parameter List for parameter communications registers.
