b43: Multi-function input terminal S1~S6 signal scan time (N. mS × 8), N = (1~100 times).
b66: AIN signal scan time (N. mS × 8), N = (1~100 times).
1.) If b43 scan time is set to say 80mS (i.e N = 10) then digital input signals on for less then 80mS will
be ignored.
2.) If the CPU scans the same input signal for N times (scan times), it is accepted as normal. If it is less
than N times, it will be taken as noise. One scan time: 8ms.
3.) User can increase scan time to counteract electromagnetic noise in the operating environment.
Increasing b43/b66 will reduce the inverter response time.
b44 – b52 Keypad, Jog and Preset Frequency setting
Note 1: - Frequency selection will be made according to status of terminals S1-
S4 & AIN and setting of parameters b35-b38 and b41 as required.
Note2:- Selected preset frequency values should be programmed into parameters
b44 – b52 as required.
1) b35 ~ b38, and b41 = 002 - 004 (Preset Frequency Command 1~3)
When a run command is applied and any of the selected multi-function input terminals are
ON, the motor will run at the preset frequency according to the table below.
2) b35 ~ b38, and b41 = 005 (Jog Frequency Command)
External input terminal is set to Jog operation. When terminal is ON, the motor will run at the
Jog frequency according to the table below.
Parameter Description Frequency range Factory default
b45 Preset frequency 1 (Hz) 00.0 - 200 05.0
b46 Preset frequency 2 (Hz) 00.0 - 200 05.0
b47 Preset frequency 3 (Hz) 00.0 - 200 10.0
b48 Preset frequency 4 (Hz) 00.0 - 200 20.0
b49 Preset frequency 5 (Hz) 00.0 - 200 30.0
b50 Preset frequency 6 (Hz) 00.0 - 200 40.0
b51 Preset frequency 7 (Hz) 00.0 - 200 50.0
b52 Preset frequency 8 (Hz) 00.0 - 200 60.0
b44 Jog frequency (Hz) 00.0 - 200 05.0
b53 Multi-function analog output:
Multi-function analog output signal select:-
001: Setting / command frequency
002: Output frequency
003: DC link voltage
004: Output current
005: PID feedback signal
b54 Multi-function analog output gain = 000 ~ 200%
0-10 Vdc is output from multi-function analog output terminal FM+.
Output can be set to correspond to any of the above values.
b54 is used to scale the output signal supplied to an externally connected analog device.
b53 = 005, PID Feedback. The analog input to terminal AIN ( 0-10Vdc or 4-20mA),will be output
from terminal FM+ as 0-10Vdc.
Note: Due to hardware limits, the max output voltage from FM+ terminal is limited to 10V.
