Measuring System
• kit motors to be installed in machines and installations; consisting of
individual components that are mounted to a moving and as static part
of the mechanical system
The controllers can be adjusted to Rexroth motors without any problem
because the manufacturer provides the respective data set for each
motor type. These data are available as parameter values.
• In the case of housing motors with data memory in the motor encoder,
the parameter values are delivered as an integral part of the motor. At
the initial commissioning they are automatically loaded to the
controller.
• In the case of kit motors (individual components) and housing motors
without data memory in the motor encoder, the respective motor
parameters are not delivered with the motor. They can be easily
loaded to the controller, however, from a data base in the "DriveTop"
commissioning tool.
The motor parameter values determined by the manufacturer guarantee
that the motor can be loaded in accordance with its operational
characteristic, if the required current and the corresponding power are
provided by controller and supply unit.
Rexroth motors are thermally monitored by the controller and protected
against overheating. To do this the current motor temperature is
determined by thermo sensors installed in the motor winding. Depending
on temperature thresholds that can be set, the controller generates a
warning or switches the motor off.
Note: Rexroth motors, by motor parameters made available and
temperature evaluation adjusted in an optimum
guarantee easy commissioning, full drive performance and a
high degree of operational safety!
As a standard, Rexroth housing motors are equipped with a position
measuring system. The individual motor series have different measuring
systems which allows offering cost-efficient motors depending on the
application.
The following measuring systems are used:
• HSF ("high-resolution servo feedback"), single- or multi-turn type
• resolver, single- or multi-turn type
Together with Rexroth kit motors it is possible to use different encoder
systems:
• encoder with sine signals and EnDat interface, 1Vpp, Heidenhain
standard
• encoder with sine signals, 1Vpp, Heidenhain standard
• encoder with square-wave signals, TTL, Heidenhain standard
• Hall sensor box and encoder with sine signals, 1Vpp, Heidenhain
standard (only for Rexroth linear kit motors)
• Hall sensor box and encoder with square-wave signals, TTL,
Heidenhain standard (only for Rexroth linear kit motors)
