For SERVO, the de-excitation time is only used for DC current braking.
Note: The parameter is calculated using p0340 = 1, 3.
For induction motors, the result depends on the rotor time constant (r0384).
if this time is shortened too much, then this can result in an inadequate de-magnetizing of the induction motor and
in an overcurrent condition when the pulses are subsequently enabled (only when the flying restart function is acti-
vated and the motor is rotating).
p0348[0...n] Speed at the start of field weakening Vdc = 600 V / Mot n_field weaken
SERVO_S110-CAN, Can be changed: C2(3), U, T
SERVO_S110-DP,
Data type: FloatingPoint32
SERVO_S110-PN
P-Group: Motor
Not for motor type: -
Min
0.0 [rpm]
Description: Sets the speed at the start of field weakening for a DC link voltage of 600 V.
Dependency: Refer to: p0320, r0331
Caution: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected. Infor-
mation in p0300 should be carefully observed when removing write protection.
p0349 System of units, motor equivalent circuit diagram data / Unit_sys mot ESB
SERVO_S110-CAN, Can be changed: C2(3)
SERVO_S110-DP,
Data type: Integer16
SERVO_S110-PN
P-Group: Motor
Not for motor type: -
Min
1
Description: Sets the actual system of units for motor equivalent circuit diagram data.
Value: 1:
Dependency: Refer to: p0304, p0305, p0310
Note: The reference parameter for resistances of the rated motor impedance Z = p0304 / (1.732 * p0305) is in the % units
system.
Inductances are converted into a resistance using the factor 2 * Pi * p0310.
If a reference parameter (p0304, p305, p0310) is zero, then it is not possible to make a changeover to "referred"
values (per unit values).
p0350[0...n] Motor stator resistance, cold / Mot R_stator cold
SERVO_S110-CAN, Can be changed: C2(3), U, T
SERVO_S110-DP,
Data type: FloatingPoint32
SERVO_S110-PN
P-Group: Motor
Not for motor type: -
Min
0.00000 [ohm]
Description: Sets the stator resistance of the motor at ambient temperature p0625.
Dependency: Refer to: p0625, r1912
Caution: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected. Infor-
mation in p0300 should be carefully observed when removing write protection.
Note: The motor identification routine determines the stator resistance from the total stator resistance minus the cable
resistance (p0352).
