Possible causes
— Kp (speed controller) too low
— Tn (speed controller) too high
— ARLPF / ARHPF too high
— ARLP2 too high
— Kp (speed controller) too high
— Tn (speed controller) too low
— ARLPF / ARHPF too low
— ARLP2 too low
— offset not correctly adjusted for
analog setpoint provision
— AGND not joined to the
controller-GND of the controls
— Motor numbers stored in the
encoder and amplifier do not
match the parameters that have
been set
— SinCos commutation
(wake&shake) not completed

Measures
— increase Kp (speed controller)
— use motor default value for
Tn (speed controller)
— reduce ARLPF / ARHPF
— reduce ARLP2
— reduce Kp (speed controller)
— use motor default value for
Tn (speed controller)
— increase ARLPF / ARHPF
— increase ARLP2
— adjust offset (analog I/O)
— join AGND and controller-GND
— default values for the motor
have been loaded, SAVE
automatically stores the
motor number in the EEPROM
— ENABLE the amplifier
