Frequency command
When b84 = 000: only UP/DOWN on the keypad can control and the setting of A01 has no
No relationship.
When b84 = 001: only VR on the keypad can control and the setting of A01 has no
relationship.

Remote mode
Run command from the run parameter A00
Frequency command from the frequency parameter A01
b85 Remote keypad control
000: Disabled
001: Enabled: Operation according to b92 if cable fault
002: Enabled: Operation at the last set frequency if cable
fault
(Stop mode by
iDrive
Keypad or parameter A00 as
appropriate).
When b85 = 001, the following parameters will be auto set:
iDrive
serial communication address: = 1 Data bits: 8 bit
Baud rated (bps): 38400 Parity: no parity
Stop bits: 1 bit
Note: 1. Connect remote keypad in stop mode; control priority is with remote keypad
2. If the remote keypad is connected in run mode, it will not be effective until the
inverter is in stop mode.
b86 Carrier frequency (kHz) : 004-016
Set this parameter from 4-16kHz as required. (Default = 10 kHz).
Note: In situations where there is excessive audible noise from the motor or it is required to
reduce electrical interference (RFI) from the inverter caused by use of long cable then
the carrier frequency can be adjusted.
•
To reduce electromagnetic interference due to long cable etc, decrease carrier frequency.
•
To reduce motor audible noise, increase carrier frequency.

Tip!
Quick changeover between
LOCAL
and
REMOTE
control modes can be made by simultaneously
pressing the
▼
/
RESET
and the
DATA/ENT
keys on keypad. Modes can be ‘toggled’ by this method.
Note that the motor must be stopped before changeover is allowed.
