1 Analog output preset valid – prevention of startup
1. Check wiring of analog predefined output to see if there is an open-circuit / loose contact.
2. When the trim function is activated (parameter 530), the default output must not be on invalid if
the Modbus communication (parameter 148 / 149) is interrupted.
2 Analog output preset valid – default output low-fire
1. Check wiring of analog predefined output to see if there is an open-circuit / loose contact.
2. When the trim function is activated (parameter 530), the default output must not be on invalid if
the Modbus communication (parameter 148 / 149) is interrupted.
