11 Screen page "Motor" synchronous
All the parameters that appear on this screen page are defined by the motor default values (internal database in
the amplifier), and in most cases it will not be necessary to alter them.
Motor Type
ASCII: MTYPE
This parameter is used to distinguish between synchronous (MTYPE = 1) and asynchronous motors (MTYPE =
3). If asynchronous is selected, then this screen page will appear in a different layout. Change this only while
the amplifier is disabled.
No. of poles
ASCII: MPOLES
The current setpoint can be set for the operation of 2- to 250-pole motors. Change this only while the amplifier is
disabled.
Io
ASCII: MICONT
The standstill current is the r.m.s. current value that the motor requires at standstill to produce the standstill
torque (defines the maximum value for the entry of Irms in the current controller).
Iomax
ASCII: MIPEAK
The peak current (r.m.s. value) should not exceed 4 x the rated current of the motor. The actual value is also
determined by the peak current of the servo amplifier that is used (defines the maximum value for the entry of
Ipeak in the current controller).
L
ASCII: L
Inductance of the motor (phase-phase). You can take this value from the motor manual.
Max. speed
ASCII: MSPEED
Maximum permissible speed of the motor. Limits the entry for the parameter SPEED LIMIT (screen page
"Speed controller").
Number / Name
ASCII: MNAME
ASCII: MNUMBER
Select the motor that is used from the motor database. The data are loaded after the motor has been selected.
If an encoder is used as a feedback unit, the motor number will automatically be reported to the servo amplifier.
Make changes only while the amplifier is disabled.
The following parameters are updated from the parameter set in the motor database:

Motor
Feedback
Current controller
Speed controller
Brake
ASCII: MBRAKE
If you want to operate a 24V holding brake in the motor directly from the servo amplifier, this parameter can be
used to enable the brake function.
In the diagram in Chapter I.9 of the Installation Manual you can see the time/function relationship between the
ENABLE signal, the speed setpoint, actual speed value, and the braking force. Change this only while the
amplifier is disabled + reset.

ID Function Comments
0 without Brake function is disabled.
If the brake function is enabled, then the output at the BRAKE (X9/2) terminal
1 with will be 24V if the ENABLE signal is present (Brake off) and 0V if the ENABLE
signal is missing (brake activated).
