DOK-INDRV*-FU*********-IB01-EN-P
This parameter only takes effect in conjunction with field-oriented current
control without encoder. Together with P-0-0590, Motor model
frequency loop proportional gain, parameter P-0-0591 is used to
parameterize the "frequency loop".
By means of the differences between motor model and measured
currents, the frequency loop determines the current rotational frequency
of the motor shaft. The output of the frequency loop supplies parameter
S-0-0040, Velocity feedback value and is transmitted according to the
velocity loop.
Note: Field-oriented current control without encoder is activated via
P-0-0045, Control word of current controller. If the
functional package "closed-loop" is active, "operation without
encoder" has to be set in P-0-0074, Encoder type 1 (motor
encoder)!

P-0-0592, Motor model adjust factor
Input min/max: Default value: Unit:
MPB: 0,000 / 1,000 0,100 --
This parameter only takes effect in conjunction with field-oriented current
control without encoder.
The drive-internal motor model calculation carried out in the current loop
clock is corrected by means of the adjust factor entered in P-0-0592 so
that the motor currents determined by means of the motor model and the
rotor flux comply with the real values.
Note: Field-oriented current control without encoder is activated via
P-0-0045, Control word of current controller. If the
functional package "closed-loop" is active, "operation without
encoder" has to be set in P-0-0074, Encoder type 1 (motor
encoder)!

P-0-0640, Cooling type
Input min/max: Default value: Unit:
MPB: 0 / 4 0 --
The motors of the MSK, MHD and MKD series can be operated in
different cooling types. Depending on the motor type, cooling can be
realized as
• standard cooling (natural convection, non-ventilated)
• surface ventilation
• liquid cooling
