NOTE.
– To communicate with the EXCRDU1 remote keypad, all the above parameters (except for the serial node address, which can be modified as you prefer) must be set to the value indicated in the table.
– In the case of use of PID control, if you follow the above configuration, the feedback signal must be connected to the first analog input AI1 of the VLB3.

*t) Motor thermally overloaded. Possible causes: – Check drive dimensioning.
– Impermissible continuous current. – Check machine/driven mechanics for excessive load.
– Too frequent acceleration processes.
– Too long acceleration processes.
0x2320 Short circuit/earth leakage – Short circuit/earth fault of motor cable – Check motor cable.
– Capacitive charging current of the motor cable too high. – Check length of the motor cable.
– Use shorter or lower-capacitance motor cable.

Possible causes: (see chapter Brake energy management on I473
– Too high braking energy. instruction).
– Too high mains voltage. – Connect brake resistor to the power unit and activate the
integrated brake chopper.
– Reduce the slip compensation gain: set P315.01=5%.
