9.5 Homing
9.5.1 Special feature PD4C USB
Note
Because this motor controller is not fitted with a field bus, the following operating mode is only usable
with a NanoJ program.
Further information on programming and use of a NanoJ program can be found in the "Programming
with NanoJ" section.
9.5.2 Overview
Description
The purpose of the reference run (homing method) is to synchronize the motor controller with the
encoder index of the motor or position switch in a system.
Activation
To activate the mode, the value "6" must be set in object 6060
h
(Modes Of Operation) (see "DS402
If a reference and/or limit switch is used, these special functions first need to be activated in the I/O
configuration (see "Digital inputs and outputs").
When using the motor in "Open Loop" mode the object 320A
h
:04 needs to be set to the value "1"
before starting the homing mode.
Control word
The following bits in object 6040
(control word) have a special function:
•
Bit 2 is used to trigger an quick stop. If it is set to "0", the motor carries out a quick stop with the
ramp set in object 6085
. The motor then goes into "Switch on disabled" mode (see the "DS402
Power State machine" section).
•
Bit 4: If the bis is set to "1", the referencing is started. This is set forth until either the reference
position is reached or bit 4 is set to "0" again.
Status word
The following bits in object 6041
(status word) have a special function:
Bit 13
Bit 12
Bit 10
