4. The result can be improved by compensating the voltage emulation error (only for
synchronous motors).
To do this, activate function module "Extended torque control (Page 485)" (r0108.1).
Determine the voltage emulation error with the stationary motor data identification
(p1909.14 = 1 and p1910).
Activate the compensation of the voltage emulation error (p1780.8 = 1).
5. If, after reaching the current setpoint, the current actual value dips, correct the current
actual value via p1734 or p1735 (see the subsequent diagram).
