Slip compensation
S P
0 ... 150 %
[ 100 ]
The slip compensation increases the output frequency, dependent on load, to keep the DC
asynchronous motor speed approximately constant.
The factory setting of 100% is optimal when using DC asynchronous motors and correct motor
data has been set.
If
several motors (different loads or outputs) are operated with one FI, the slip compensation
P212 must be set to 0%. This rules out a negative influence. This is equally valid for
synchronous motors that do not have slip due to their design.
P213 ISD control loop gain
S P
25 ... 400 %
[ 100 ]
This parameter influences the control dynamics of the FI current vector control (ISD control).
Higher settings make the controller faster, lower settings slower.
Depending on the type of application, this parameter can be altered, e.g. to avoid unstable
operation
P214 Lead torque
S P
-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: Motor torques (with rotation field right) are entered with a positive sign, generator
torques are entered with a negative sign. The reverse applies for the counter
clockwise rotation.
P215 Boost precontrol
S P
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
at 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.
P216 Time boost precontrol
S P
0.0 ... 10.0 s
[ 0 ]
Only with linear characteristic curve (P211 = 0% and P212 = 0%).
Application time for increased starting current.
