Chapter 12 Descriptions of Parameter SettingsC2000 Plus
12.1-05-2
Pr.01-01 and Pr.05-04 determine the maximum rotor speed for IM.
For example: Pr.01-01=20 Hz, Pr.05-04=2, according to the equation 120 x 20 Hz / 2 = 1200 rpm
and take integers. Due to the slip of the IM, the maximum setting value for Pr.05-03 is 1199 rpm
(1200 rpm – 1).
05-04
Number of Poles for Induction Motor 1
Default: 4
Settings 2–64
Set the number poles for the motor (must be an even number).
Set up Pr.01-01 and Pr.05-03 before setting up Pr.05-04 to make sure the motor operates normally.
Pr.01-01 and Pr.05-03 determine the maximum set up number poles for the IM.
For example: Pr.01-01 = 20 Hz and Pr.05-03 = 39 rpm, according to the equation 120 x 20 Hz /
39 rpm = 61.5 and take even number, the number of poles is 60. Therefore, Pr.05-04 can be set
to the maximum of 60 poles.
05-05
No-Load Current for Induction Motor 1 (A)
Default: Depending on the
model power
Settings 0.00–Pr.05-01 default
For model with 110 kW and above, default setting is 20% of motor rated current.
05-06
Stator Resistance (Rs) for Induction Motor 1
Default: Depending on the
model power
Settings 0.000–65.535 W
05-07
Rotor Resistance (Rr) for Induction Motor 1
Default: Depending on the
model power
Settings 0.000–65.535 W
05-08
Magnetizing Inductance (Lm) for Induction Motor 1
Default: Depending on the
model power
Settings 0.0–6553.5 mH
05-09
Stator Inductance (Lx) for Induction Motor 1
Default: Depending on the
model power
Settings 0.0–6553.5 mH
