STOP key priority
If H96=1 or 3, pressing the key on the keypad forces the
inverter to decelerate and stop the motor even if the inverter is
running by any run commands given via the terminals or
communications (link operation). After the motor stops, the inverter
issues alarm Er6.
Er6
Start check function The inverter prohibits any run operations and displays Er6 on the 7-
segment LED monitor if any run command is present when:
- Powering up
- An alarm is released (the
key is turned ON or an
alarm reset RST is input.)
- "Enable communications link LE" has been activated
and the run command is active in the linked source.
Er7 Tuning error detection During tuning of motor parameters (auto tuning), one of the
following errors happened:
- tuning has failed.
- tuning has been aborted (for example, by removing run
command)
- an abnormal condition has been detected.
Er8 RS485
communications error
detection
The inverter is connected to a communications network via the
RS485 port of the keypad and a communications error has been
detected.
ErF Data save error during
undervoltage
The data could not be saved during activation of the undervoltage
protection function.
ErP RS485
communications error
detection (Optional)
The inverter is connected to a communications network via the
optional RS485 communications card (OPC-E1-RS) and a
communications error has been detected.
ErH Hardware error Hardware error due to:
- Poor connection between the control printed circuit board
(control PCB) and the power printed circuit board (power
PCB), interface printed circuit board (interface PCB) or
option card.
- Short circuit between terminals 11 and 13.
Err Mock Alarm Simulated alarm that can be generated by setting H45=1. This
allows to check the fault sequence in an electrical system.
PG PG disconnection The signal from the PG has been disconnected when PG feedback
card is been used.
