Parameter Function
P0347[0...2] Demagnetization time [s]
Changes time allowed after OFF2/fault condition, before pulses can be re-enabled.
Dependency: See P0341
Notice: Not active following a normally completed ramp-down, e.g. after OFF1, OFF3 or JOG. Overcurrent trips
will occur if the time is decreased excessively.
Note: The demagnetization time is approximately 2.5 x rotor time constant in seconds. Default value is depend-
ing on converter type and its rating data.
P0350[0...2] Stator resistance (line) [Ω]
Stator resistance value for connected motor (line value). The parameter value doesn't include the cable
resistance.
Dependency: See P0341
Note: There are three ways to determine the value for this parameter:
Calculate using
•
– P0340 = 1 (data entered from rating plate) or
– P0010 = 1, P3900 = 1, 2 or 3 (end of quick commissioning).
Measure using P1900 = 2 (standard motor data identification - value for stator resistance is overwrit-
•
ten).
Measure manually using an Ohmmeter.
•
Since the manually measured resistor is a line-to-line value, which includes the cable resistors, the meas-
ured value has to be divided by two and the cable resistor of a line has to be subtracted from that value.
The value entered in P0350 is the one obtained by the method last used. Default value is depending on
converter type and its rating data.
P0352[0...2] Cable resistance [Ω]
Cable resistance value between converter and motor for one phase.
Dependency: See P0341
P0354[0...2] Rotor resistance [Ω]
Sets rotor resistance of motor equivalent circuit (phase value).
Dependency: Calculated automatically using the motor model or determined using P1900 (motor identification). This
parameter is influenced by automatic calculations defined by P0340.
P0356[0...2] Stator leakage inductance
[mH]
Sets stator leakage inductance of motor equivalent circuit (phase value).
Dependency: See P0354
P0358[0...2] Rotor leakage inductance
[mH]
Sets rotor leakage inductance of motor equivalent circuit (phase value).
Dependency: See P0354
P0360[0...2] Main inductance [mH]
Sets main inductance of the motor equivalent circuit (phase value).
Dependency: See P0354
Caution: The data of equivalent circuit relates to the star equivalent circuit. Any data of the delta equivalent circuit
available therefore must be transformed to the star equivalent circuit before entering into the converter.
