C47 Remote keypad
control selection
000: Disable
001: Enable. Operation determined by parameter F09 on signal loss
002: Enable. Operation at the last set frequency on signal loss
(Stop mode by Inverter keypad or F04 parameter as configured)
1.) Before installing the remote keypad, set C47 to 001 or 002 via the main keypad, then POWER
DOWN the inverter and install the remote keypad.
2.) When C47=001, parameters C49 - C53 will be auto set as follows:
Inverter communication address: No. 1
Data bytes: 8 bit
Baud rate: 38400 (bps)
Parity: no parity
Stop bits: 1
3.) Set C47 = 000 via the main keypad after the remote keypad is removed.
4.) C47 can‘t be changed by the remote keypad.
NOTES: 1. For safety reasons, install or remove remote keypad only when the power
is OFF.
2. If the remote keypad is installed while the power is ON and in stop mode, the
inverter will be controlled by the remote keypad.
3. If the remote keypad installed while the power is ON and in run mode, the
Inverter will be controlled by the main keypad. The remote keypad control will
not be effective until the inverter has stopped.
C48 Copy module
000: Copy module disabled
001: Copy to module from inverter (read)
002: Copy to inverter from module (write)
003: Read/ write check (compare the parameters)
NOTE: Module copy function is applicable only to inverters with the same voltage and kW rating.
C49 sets the communication address, for the specific inverter when multi-inverters are controlled.
C49 Inverter communication address: 001 - 254
