H11 Deceleration Mode
H11 specifies the deceleration mode to be applied when a run command is turned OFF.
Data for H11
0
1
When reducing the reference frequency, the inverter decelerates the motor
according to the deceleration commands even if H11 = 1 (Coast-to-stop).
Instantaneous Overcurrent Limiting (Mode selection)
H12
Refer to the descriptions of F43 and F44.
Restart Mode after Momentary Power Failure
H13, H14
(Restart time, Frequency fall rate, Continuous running level, and Allowable
H15, H16
momentary power failure time)
For how to set these function codes (Restart time, Frequency fall rate, Continuous running
level and Allowable momentary power failure time), refer to the description of F14.
H26, H27 Thermistor (for motor) (Mode selection and Level)
These function codes specify the PTC (Positive Temperature Coefficient) thermistor
embedded in the motor. The thermistor is used to protect the motor from overheating or
output an alarm signal.
Thermistor (for motor) (Mode selection) (H26)

H26 selects the function operation mode (protection or alarm) for the PTC thermistor as
shown below.

Normal deceleration
Coast-to-stop
The inverter immediately shuts down its output, so the motor stops according
to the inertia of the motor and machinery (load) and their kinetic energy losses.
Disable
Enable
When the voltage sensed by PTC thermistor exceeds the detection level, the motor
protective function (alarm OH4) is triggered, causing the inverter to enter an alarm
stop state.
Enable
When the voltage sensed by the PTC thermistor exceeds the detection level, a motor
alarm signal is output but the inverter continues running. You need to assign the
"Motor overheat detected by thermistor" signal (THM) to one of the digital output
terminals beforehand, by which a temperature alarm condition can be detected by the
thermistor (PTC) (E20 to E24 and E27, data = 56).
