DOK-INDRV*-FU*********-IB01-EN-P
P-0-3600 – P-0-4095 (General Device Parameters)
P-0-4004, Magnetizing current
Input min/max: Default value: Unit:
MPB: 0,000 / var. 1,000 A eff
In the case of asynchronous motors, the nominal magnetizing current
defined by Bosch Rexroth is entered in this parameter. The actually
flowing magnetizing current in the base speed range results by
multiplication of the value of P-0-4004 with P-0-0532, Premagnetization
factor. In the field weakening range the magnetizing current, with
increasing speed, is reduced by the flux loop based on the value of this
product.
Note:
Writing the correct value to this parameter:
• In the case of Rexroth motors of the 2AD, ADF lines and in
the case of linear and rotary kit motors, by loading the
motor parameters with the commissioning software (e.g.
IndraWorks).
• In the case of other asynchronous motors: manual input
according to manufacturer's specification.
• In the case of synchronous motors, the parameter is not
used and automatically set to A
eff
= 0.

Measuring Systems"
P-0-4005, Flux-generating current, limit value
Input min/max: Default value: Unit:
MPB: var. / 0,000 0,000 A eff
In this parameter a negative limit value for the flux-generating current can
be entered.
This limit value is available for field weakening operation of synchronous
motors and therefore exclusively takes effect for synchronous motors for
which field weakening operation was allowed (see parameter P-0-0045,
Control word of current controller).
Note:
Writing the correct value to this parameter:
• In the case of Rexroth motors of the MHD, MKD, MKE and
MSK lines, automatically at initial commissioning.
• In the case of linear and rotary synchronous kit motors by
loading the motor parameters with the commissioning
software (e.g. IndraWorks).
• In the case of other synchronous motors: manual input
according to manufacturer's specification.
• In the case of asynchronous motors, this parameter is
automatically set to A
eff
= 0.
