Vmot is motor rated voltage in Vrms
Vmax is motor maximum used speed
Evaluation of Pr16 and Pr17 (speed regulator gain)
The default values of Pr16 and Pr17 have been chosen considering identical motor and drive
rated currents; if this is not the case correct the values of parameters Pr16 and Pr17 with the
ratio of the motor rated current/drive rated current. Preventive execution of this compensation
will eliminate the risk of motor vibration at the first start-up.
6)
Set the analogue reference signal to 0 V (terminals 1, 2 of board X2), and enable the drive (24
V on terminal 11 of board X3 ).
7)
The motor shaft must be stopped; when the analogue reference voltage is changed motor speed
should change proportionally. If this is not the case check your wiring.
8)
Save your changes with b99.15.
The drive is preset with default values designed to meet the requirements of the majority of
applications. With the default values the pico-PLC in the drive runs the program described in
appendix G, so the following functions will be present on the input and output terminal boards:
