P214
Lead torque
P
Always visible
-200 ... 200 %
[ 0 ]
This function allows a value for the expected torque requirement to be set in the controller. This
function can be used in lifting applications for a better load transfer during start-up.
Note:
With a field of rotation to the right, the motor torques are entered with a positive
sign. Generator torques are entered with a negative sign. For rotation field to the
left, the reverse applies.
P215
Boost precontrol
P
Always visible
0 ... 200 %
[ 0 ]
Only with linear characteristic curve (P211 = 0% and P212 = 0%).
For drives that require a high starting torque, this parameter provides an option for switching in an
additional current during the start phase. The application time is limited and can be selected in the
parameter >Time boost precontrol< P216.
All current and torque current limits that may have been set (P112 and P536, P537) are
deactivated during the boost lead time.
Note:
With active ISD control (P211 and / or P212 ≠ 0%), parameterisation of P215 ≠ 0
results in incorrect control.
P216
Time boost precontrol
P
Always visible
0.0 ... 10.0 s
[ 0 ]
Only with linear characteristic curve (P211 = 0% and P212 = 0%).
Application time for increased starting current.
Note:
With active ISD control (P211 and / or P212 ≠ 0%), parameterisation of P216 ≠ 0
results in incorrect control.
