Checking all electrical and mechanical components

The following points have to be noted when commissioning MBT motors in
particular:
MBT motors are kit motors whose single components are - completed by an
encoder system - directly installed into the machine by the manufacturer. As
a result, kit motors do not feature any data memory to provide motor parame‐
ters, standard controller settings, etc. All parameters must be manually en‐
tered or loaded to the drive during commissioning. The commissioning pro‐
gram from Rexroth provides all Rexroth motor parameters.
The encoder polarity has to be set before the commutation is adjusted, taking
the direction of rotation of the rotor into account.
Also see
chapter 13.6 "Determining the polarity of the encoder system" on
page 389
and
fig. 13-2 "Direction of rotation of the rotor, as viewed from the
cable output side at the stator (MST)" on page
At MBT motors, the position of the rotor to the stator has to be determined
immediately after power-up or a malfunction. This is referred to as pole posi‐
tion detection or commutation adjustment. This means that the commutation
adjustment is the establishment of a position reference to the electrical or
magnetic model of the motor. The commutation adjustment method depends
on the encoder type used.
In addition to the motor documentation contained herein, commissioning of
the motors requires the following documents:
●
Rexroth IndraDrive Firmware for Drive Controllers, Functional Descrip‐
tion, DOK-INDRV*-MP*-02VRS**-FK□□-□□-P
●
Rexroth IndraDrive Drive Controllers, Parameter Description, DOK-
INDRV*-GEN-**VRS**-PA□□-□□-P
●
Rexroth
IndraDrive
**VRS**-WA□□-□□-P
The following requirements have to be met to ensure successful commission‐
ing:
●
Compliance with safety-related guidelines and instructions
●
Check of electrical and mechanical components for reliable functioning
●
Availability and provision of required tools
●
Adherence to the commissioning procedure described below
Check all electrical and mechanical components prior to commissioning and
pay particular attention to the following issues:
