p0314[0...n] Motor pole pair number / Mot pole pair No.
Access level: 3
Can be changed: C(1, 3)
Min
0
Description: Sets the motor pole pair number.
Values:
p0314 = 1: 2-pole motor
p0314 = 2: 4-pole motor
etc.
Dependency: For p0314 = 0, the pole pair number is automatically calculated from the rated frequency (p0310) and the rated
speed (p0311) and displayed in r0313.
Notice: If p0314 is changed during quick commissioning (p0010 = 1), then the maximum speed p1082, which is also asso-
ciated with quick commissioning, is appropriately pre-assigned.
For induction motors, the value need only be input if the rated data of a generator is entered therefore resulting in a
negative rated slip. In this case, the number of pole pairs in r0313 is too low by 1 and must be manually corrected.
p0316[0...n] Motor torque constant / Mot kT
Access level: 3
Can be changed: C(1, 3), U, T
Min
0.00 [Nm/A]
Description: Sets the torque constant of the synchronous motor.
p0316 = 0: The torque constant is calculated from the motor data.
p0316 > 0: The selected value is used as torque constant.
Dependency: Refer to: r0334
Caution: This parameter is automatically preset for motors from the motor list (p0301). When selecting a catalog motor, this
parameter cannot be changed (write protection). Information in p0300 should be carefully observed when removing
write protection.
Note: This parameter is not used for induction motors (p0300 = 1xx).
p0318[0...n] Motor stall current / Mot I_standstill
Access level: 4
Can be changed: C(3)
Min
0.00 [Arms]
Description: Sets the stall current for synchronous motors (p0300 = 2xx).
Caution: This parameter is automatically preset for motors from the motor list (p0301). When selecting a catalog motor, this
parameter cannot be changed (write protection). Information in p0300 should be carefully observed when removing
write protection.
Note: The parameter is used for the I2t monitoring of the motor (refer to p0611).
This parameter is not used for induction motors (p0300 = 1xx).
