H86 to H90 Reserved for particular manufacturers
H86 to H90 are reserved for particular manufacturers. Do not modify the settings.
H91 PID Feedback Wire Break Detection
Using the terminal [C1] (current input) for PID feedback signal enables wire break detection and alarm (
cof
) issuance.
H91 specifies 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 time)
H92, H93 Continuity of Running (P and I)
(Refer to F14.)
H94 Cumulative Motor Run Time 1
(Refer to H44.)
H95 DC Braking (Braking response mode)
(Refer to F20 through F22.)
H96 STOP Key Priority/Start Check Function
H96 specifies a functional combination of "STOP key priority" and "Start check function" as listed below.
Data for H96 STOP key priority Start check function
0 Disable Disable
1 Enable Disable
2 Disable Enable
3 Enable Enable
„ STOP key priority
Even when run commands are entered from the digital input terminals or via the RS-485 communications link (link
operation), pressing the
key 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
one has been turned ON, the inverter does not start up but displays alarm code
er6 on the LED monitor.
• When the power to the inverter is turned ON.
• When the key is pressed to release an alarm status or when the digital input terminal command
RST
("Reset alarm")
is turned ON.
• When the run command source is switched by a digital input terminal command such as
LE
("Enable communications
link via RS-485 or fieldbus") or
LOC
("Select local (keypad) operation").
H97 Clear Alarm Data
H45 (Mock Alarm)
H97 clears alarm data (alarm history and relevant information) stored in the inverter.
To clear alarm data, simultaneous keying of " key +
key" is required.
Data for H97 Function
0 Disable
1
Enable (Setting "1" clears alarm data and then returns to "0.")
