where: InM is rated motor current at zero rpm in Ampere
InD is rated drive current in Ampere
The maximum value of Pr33 is 50.0 except for HPD20N because the
limit is 31.
Pr19 calculation (peak current)
The maximum value must be no higher than three times the value of Pr33
Pr29 calculation (number of poles)
Use the following table for MB series motors
Flange ( mm ) Pr29
56 4
70 4
105 8
145 8
205 8
Pr32 calculation (rated speed)
If Pb 42.6=0 Pr32 = Vmax 1.12

where: ω is nominal motor speed in rad/sec
Vmain is HPD power supply in Vrms
Vmot is motor rated voltage in Vrms
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.
