Observe the restrictions in conjunction with the commutation off‐
set determination when using synchronous motors! See firmware
documentation, chapter "Drive Control", "Commutation Setting".
Possibly available reluctance property cannot be used for syn‐
chronous third-party motors! For third-party motors, it is impossi‐
ble to determine fail-safe motor parameter values for using the re‐
luctance property. The respective bit of "P-0-4014, Type of con‐
struction of motor" therefore mustn't be set!
Requirements on Third-Party Motors
General Information
For successful and fail-safe use of a third-party motor, check
● whether the third-party motor to be controlled satisfies the voltage loads
● which drive controller is suitable due to the motor torques to be deliv‐
ered
● whether the third-party motor has the required minimum inductance
● whether the motor can be protected against inadmissible temperature
rise in the case of overload (temperature evaluation)
● whether the mounted position measuring system can be evaluated by
the drive controller or which position measuring system can be selected
for kit motors
Voltage Load of the Third-Party Motor
The voltage load of the insulation system of a motor occurring in practical ap‐
plication is mainly influenced by the following characteristics:
● The output variables of the drive controller which is used (feed the trans‐
mission distance)
● Cable parameters depending on cable design and length (determine the
properties of the transmission distance, such as the attenuation)
● The motor design regarding capacitive and inductive properties (form
the end of the transmission distance)
As a result of the variables, the insulation system of the third-party motor, as
regards voltage, is loaded by the following values:
● Periodic peak voltage U
pp
and
● Voltage change dv/dt
The occurring periodic peak voltages at the motor terminals are caused by
reflections at the motor cable end. The insulation of the motor is thereby loa‐
ded with a higher peak voltage than the one occurring at the output of the
power section.
Determine the occurring voltage load at the terminals of the third-
party motor in the application with all involved components.
Using the HMF Motor Filter
Use voltage-reducing components (e.g. motor filter HMF), if one of the follow‐
ing criteria applies:
● Allowed voltage change (dv/dt) of third-party motor: < 5 kV/μs
● With mains voltage 3 AC 230 V … 500 V:
Allowed periodic peak voltage (crest value) of third-party motor between
phase-phase and phase-housing: < 1,500 V
