Chapter 12 Description of Parameter SettingsCP2000
12.1-05-2
Set up Pr.01-01 and Pr.05-03 before setting up Pr.05-04 to make sure 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 /
39rpm=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 0.0–Pr.05-01 default
The default is 10–40% of motor rated current.
For model with 110 kW and above, default setting is 20% of motor rated current.
Stator Resistance (Rs) for Induction Motor 1
Default: Depending on
the model power
Settings 0.000–65.535 Ω
Rotor Resistance (Rr) for Induction Motor 1
Default: 0.000
Settings 0.000–65.535 Ω
Magnetizing Inductance (Lm) for Induction Motor 1
Stator inductance (Lx) for Induction Motor 1
Default: 0.0
Settings 0.0–6553.5 mH
Full-load Current for Induction Motor 2 (A)
Default: Depending on
the model power
Settings Depending on the model power
Set this value according to the rated current of the motor as indicated on the motor nameplate.
The default is 90% of the drive’s rated current.
Example: The rated current for a 7.5 HP (5.5 kW) motor is 25 A. The default is 22.5 A.
The setting range is between 2.5–30 A. (25*10%=2.5 A and 25*120%=30 A)
Rated Power for Induction Motor 2 (kW)
Default: Depending on
the model power
Settings 0.00–655.35 kW
Set the rated power for motor 2. The default is the drive’s power value.
