Chap. 9 FUNCTION CODES
After the current setting has expired, set a value for the next maintenance in H79
and press the
key so that the output signal is reset and counting restarts. This
function is exclusively applies to the 1st motor.
Check the startup times remaining before the next maintenance with
5_35
on
Menu #5 "Maintenance Information" of the keypad.
H80
Output Current Fluctuation Damping Gain for Motor 1
A41 (Output Current Fluctuation Damping Gain for Motor 2)
The inverter output current driving the motor may fluctuate due to the motor characteristics
and/or backlash in the machinery (load). Modifying the H80 data adjusts the controls in order
to suppress such fluctuation. However, as incorrect setting of this gain may cause larger
current fluctuation, do not modify the default setting unless it is necessary.
- Data setting range: 0.00 to 0.40
H89 Electronic Thermal Overload Protection for Motor (Data retention)
H89 specifies whether to retain the cumulative data of the electronic thermal overload
protection for motor when the power is shut down.
Data for H89 Function
0
Clear the cumulative data of the electronic thermal overload protection for
motor the moment the power is turned ON after the power is shut down.
1
Retain the cumulative data of the electronic thermal overload protection for
motor when the power is shut down.
H91 PID Feedback Wire Break Detection (Terminal [C1])
Using terminal [C1] (Current input) for PID feedback signals enables wire break detection
and alarm (
cof
) issuance. H91 specifies whether or not to enable the wire break detection
and the duration of detection. (The inverter judges an input current less than 2 mA on terminal
[C1] as a wire break.)
Expanding the input range of terminal [C1] to "0 to 20 mA DC" with function code C40
disables the PID feedback wire break detection.
- Data setting range: 0.0 (Disable wire break detection)
0.1 to 60.0 (s) (Detect wire break after the specified duration and issue
cof
alarm)
