before SW 2.4, the following is valid:
... displays the rated current of the power section (i-rated in A RMS) at the selected pulse fre-
quency (P1100).
from SW 2.4 the following is valid:
... displays the rated current of the power section (i-rated in A RMS) for the standard pulse fre-
quency setting (P1100). The reduction factor for higher pulse frequencies is displayed in P1099.

SRM:
The torque constant (kT) is the quotient of rated torque/rated current (RMS) for synchronous
motors with permanent excitation.
SLM:
The force constant is the quotient of the rated force/rated current (RMS) for linear per-
manent-magnet synchronous motors.

SRM:
The voltage constant is measured as induced voltage (EMF) under no load conditions at n =
1000 RPM as RMS value between the motor terminals (phase-to-phase).
SLM:
The voltage constant is measured as induced voltage (EMF) under no load conditions at v = 1
m/s as RMS value between the motor terminal and star point (phase).
