H91
PID feedback wire break
Using the terminal [C1] (current input) for PID control feedback signal enables wire break detection and
alarm (
cof
alarm) issuance. Function code H91 sets whether the wire break detection is enabled, or the
duration of detection. (The inverter judges an input current to the terminal [C1] below 2 mA as a wire break.)
- Data setting range: 0.0 (Disable alarm detection)
0.1 to 60.0 (s) (Detect wire break and issue (
cof
alarm) within the set time)
H92, H93
Operation Continuation (P, I) (See F14)
For setting of operation continuation (P, I), see the description of the function code F14.
H94
Motor Cumulative Run Time 1 (See H78)
For setting of motor cumulative run time 1, see the description of the function code H78.
H95
DC Braking (Characteristics Selection) (See F20 to F22)
For DC braking, see the descriptions of function codes F20 through F22.
H96
STOP Key Priority/Start Check Function
H96 sets a functional combination of "
key priority" and "Start check function" as listed below.

STOP key priority function
Even when run commands are entered from the digital input terminals or via the RS-485 communications
link (link operation), pressing the
key on the keypad forces the inverter to decelerate and stop the motor.
After that,
er6
appears on the LED monitor.
Start check function
For safety, this function checks whether any run command has been turned on or not in each of the following
situations. If any operation command is on, the inverter does not start the operation but displays alarm code
er6
on the LED monitor.
- When the power is turned on.
- When the
key is pressed to release an alarm status or when the digital input alarm (abnormal) reset
RST is input.
- When the link operation select
LE of the digital input or local command select LOC is input, and when the
operation command setting method is switched.
