Motor data and controller adjustments of the synchronous motor
dr.26 = EMK
eff
x √ 2
No decimal places can be entered in parameter dr.26 for the EMC. The voltage per 1000 rpm at high-frequency
motors is partly very low, that an integer setting falsies the EMC value. Parameter dr.63 (DSM EMC HR) can
be used for higher accuracy.
In order that there is a downward compatibility to older parameter lists, the parameter can be deactivated with
value "0: off".
The maximum permissible speed which is displayed in ru.79 (abs. speed [EMC]) is also calculated from the
EMC. The maximum DC link voltage, UZKmax, can be found in the power circuit manual.

The standstill continuous current affects the electronic motor protection function (see chapter 7.13.).
7.6.1.2 Controllerconguration
Parameter cS.00 must set to value 4: "speed control" for closed-loop operation.

7.6.1.3 Actual value source
The actual value source for speed control must be selected in parameter cS.01 .
Possible values for drives with speed encoder are 0 (speed measurement via encoder interface channel 1) or
1 (speed measurement via encoder interface channel 2).
Description of the correct parameter setting of the encoder interfaces is made in chapter 7.11 "Speed measure-
ment". cS.01 = 2 (calculated actual value) must be selected at operation without speed encoder (only SCL).

With activation of the system inversion it is reached that the motor with selected rotation direction "forward"
(e.g. by setpoint- or rotation setting) has the physically direction "reverse" respectively at setting "reverse" the
physical rotation "forward". Precondition is a correct wiring of motor and speed feedback (if available).
