Chapter 12 Description of Parameter SettingsC2000-HS
 Pr.01-01 and Pr.05-04 determine the maximum rotor speed for IM.
For example: Pr.01-01=20Hz, 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 1199rpm
(1200rpm – 1).
Number of Poles for Induction Motor 1
Settings
 Sets 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 20Hz / 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.
No-load Current for Induction Motor 1 (A)
Settings
 For model with 110kW and above, the default is 20% of motor rated current.
Stator Resistance (Rs) for Induction Motor 1

FOC Bandwidth for Speed Observer

Settings
 Setting the speed observer to a higher bandwidth can shorten the speed response time, but
creates greater noise interference during the speed observation.
