5 START-UP
In Its basic configuration the drive can control both synchronous permanent magnet motors
(brushless) and asynchronous induction motors, with feedback. The setting of Pr217 can select either
of the following:
Pr217=0
synchronous motor (default setting).
Pr217=1
asynchronous motor.
The drive is supplied with default factory parameter settings.
See the following chapters for use and start-up.
5.1 Setting the default parameters
If you want to set the default values of the converter as it was supplied by the manufacturer, do the
following
- power off the converter using the hardware (pin 6 of I and II axis)
- connect only 24Vdc
- power on the drive
- set b99.7 and b99.13 to 0
- issue the command b99.12
-
save the set up using commands b99.14 and b99.15.
5.2 Selection of motor type
The first time the converter is powered up, or following a default command, the drive indicates a
“dEF” condition (alarm Pr23=15).
In order to leave the drive’s initial condition, the operator shall have to input the motor data.
The parameters defining motor types are as follows:
Pr29 Number of motor poles N.
Pr32 Rated speed of the motor r.p.m.
Pr33 rated motor current (ex. 2.5A, write 2.5) A
Pr34 number of resolver poles N.
Pr46 phase-phase motor resistance (ex. 1,8Ω, write 1.8) ohm
Pr47 phase-phase motor inductance (ex. 2.6mH, write 2.6) mH
With asynchronous motors, the values above shall be supplemented with the following parameters:
Pr217 = 1
Pr218 base speed r.p.m.
Pr219 slip r.p.m.
Pr220 magnetizing current (*) A
