of A1-04 (Number of pole pairs of resolver). Then re-perform motor auto-tuning and
perform motor trial running.
3) If the motor oscillates or runs with low frequency noise, weaken the speed loop and
the current loop appropriately. For example, decrease the values of F2-00, F2-03,
F2-13, F2-14, F2-15 and F2-16, and increase the values of F2-01 and F2-04.
4) If the motor rotational speed is not steady, enhance the speed loop and the current
loop appropriately. For example, increase the values of F2-00, F2-03, F2-13, F2-14,
F2-15 and F2-16, and decrease the values of F2-01 and F2-04
The parameters of speed loop and current loop are defined in group F2.
The speed loop and current loop response directly affects pressure stability. Set stronger speed
loop and current loop response if allowed.
3.4.3 Setting and Auto-tuning of Motor Parameters
Parameter Setting
The IS300 controls the servo pump in closed-loop vector control (CLVC) mode. This mode
requires accurate motor parameters. To guarantee good driving performance and running
efficiency, set the motor parameters strictly according to the nameplate of the standard
adaptable motor. The following table lists the parameters to be set.
