Chapter 12 Description of Parameter SettingsC2000
12.2-00-6
Number of Poles for Induction Motor 1
Default: 4
Settings 2–64
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)
Default: Depending on
the model power
Settings 0 to the factory setting in Pr.05-01
For model with 110kW and above, default setting is 20% of motor rated current.
Stator Resistance(Rs) for Induction Motor 1
Default: Depending on
the model power
Settings 0.000–65.535Ω
Rotor Resistance(Rr) for Induction Motor 1
Default: 0.000
Settings 0.000–65.535Ω
Magnetizing Inductance (Lm) for Induction Motor 1
Stator inductance (Lx) for Induction Motor 1
Default: 0.0
Settings 0.0–6553.5mH
FOC Bandwidth for Speed Observer
Default:40.0
Settings 20.0–100.0Hz
Setting the speed observer to a higher bandwidth could shorten the speed response time, but
creates greater noise interference during the speed observation.
System Control
Default: 0000h
Settings bit0: Auto-tuning for ASR and APR
bit1: Inertia estimate (only in FOCPG mode)
bit2: Zero servo
bit6: 0Hz linear-cross
bit7: Save or do not save the frequency
bit8: Maximum speed for point-to-point position control
