Chapter 12 Description of Parameter SettingsME300
12.1-05-3
Stator Resistance (Rs) for Induction Motor 2
Rotor Resistance (Rr) for Induction Motor 2
Default: #.###
Settings 0.000–65.535 Ω
Magnetizing Inductance (Lm) for Induction Motor 2
Stator Inductance (Lx) for Induction Motor 2
Default: #.#
Settings 0.0–6553.5 mH
Multi-motors (Induction) Selection
Default: 1
Settings 1: Motor 1
2: Motor 2
Sets the motor operated by the AC motor drive. Multi-motors selection only supports single
control mode. For example, when you set motor 1 as SVC control mode, the control mode of
motor 2 is also set as SVC.
Frequency for Y-connection / Δ-connection Switch for an Induction Motor
Default: 60.00
Settings 0.00–599.00 Hz
Y-connection / Δ-connection Switch for an Induction Motor
Default: 0
Settings 0: Disable
1: Enable
Delay Time for Y-connection / Δ-connection Switch for an Induction Motor
Default: 0.200
Settings 0.000–60.000 sec.
You can apply Pr.05-23–Pr.05-25 in a wide range of motors, and the motor coil executes the
Y-connection / ∆-connection switch as required. The wide range motors are related to the motor
design. In general, the motor has higher torque with low speed Y-connection and has higher
speed with high speed ∆-connection
Pr.05-24 enables and disables the switch of Y-connection / ∆-connection.
When you set Pr.05-24 as 1, the drive uses the Pr.05-23 setting and current motor frequency,
and switches the current motor to Y-connection or ∆-connection. You can switch the relevant
motor parameter settings simultaneously.
Pr.05-25 sets the switch delay time of Y-connection / ∆-connection.
When the output frequency reaches the Y-connection / ∆-connection switch frequency, the drive
delays according to Pr.05-25 before activating the multi-function output terminals.
