Current Limit P2.2.7 Defines the maximum motor current from the inverter. If the output
current exceeds the value set in parameter P2.2.7 the output frequency is
lowered until the current drops below the current limit. The rate of
lowering the frequency depends on the current overshoot.
To avoid motor overloading, set this parameter according to the rated
current of the motor (normally 1,5....2xIn). In multimotor drives nominal
currents must be summarized.
Note! The value must be limited to Drive maximum output current (1
minute value).
Min Freq S1 P2.2.8 Minimum frequency direction 1.
Hoisting application: Smaller value than factory setting is not allowed to
use
0 – Max Freq S2, Hz

Zero Freq Volt P2.2.15 Output voltage at zero frequency, % of motor nominal voltage. 0 – 40 %
U/f Mid Volt P2.2.16 Voltage in the selected middle point frequency, % of motor nominal
voltage. 0 – 100 %
U/f Mid Freq P2.2.17 Middle point frequency. 0 – 250 Hz
Torque Boost P2.2.18 Torque maximization. 0 = Off
1 = On
RS Voltage Drop P2.2.19 Relative value of motor stator impedance voltage drop. Value of this
parameter is calculated by formula given below.

Stop Function P2.2.20 Stopping mode selection
Ramping: When the drive command is switched off the motion is stopped
according to the set deceleration ramp.
Brake: When the drive command is switched off the motor current is cut
off and the motion is stopped by the mechanical brake.
0 = Brake
1 = Ramping

Flux Current Kp P2.3.1 Gain for flux current control. Too small or too large value results
oscillation in the current control. Must not be changed. 0 - 32000
Flux Current Ti P2.3.2 The integration time of the flux current control. Too small or too large
value results oscillation in the current control. Must not be changed. 0 – 1000 ms
S2 Flux Control P2.3.3 Increases or decreases the Flux Current controller values P2.3.1&2 to
direction S2. Must not be changed. Used in hoisting application. 0 – 100 %
Freq 0 P2.3.4 Constant current mode frequency limit in percentage of nominal
frequency. Between 0 Hz and Freq 0 current control keeps motor current
in value of P2.3.12 Zero Speed Current. 0 – 100 %
