Commissioning: Linear motor with 2 identical primary sections

General If it is certain that the EMF of both motors have the same relative
information phase position to one another, the connecting cables can be connected
in parallel and operated from one drive.
Linear motors, which are connected in parallel, are commissioned,
based on the commissioning of a single linear motor.
First, only one linear motor (motor 1) is connected to the drive, and is
commissioned as individual motor (1FNx ...). The angular commutation
offset is automatically determined and noted.
Instead of motor 1, motor 2 is connected and is commissioned as indi-
vidual motor. Also here, the angular commutation offset is automatically
determined and noted.
If the difference between the angular commutation offset of motor 1
and motor 2 is less than 10 degrees electrical, both motors can be con-
nected in parallel to the drive and commissioned as a parallel circuit
configuration of 2 linear motors (e.g. 2 S 1FN1xxx).
Procedure for Linear motors connected in parallel are commissioned as follows:
commissioning
1. Disconnect the parallel circuit
linear motors
connected in
parallel
2. Commission motor 1 as a single motor
3. Traverse the axis and check that it is functioning correctly
4. Note the angular commutation offset of motor 1
5. Power–down and wait until the DC link has been discharged
6. Instead of motor 1, connect motor 2 to the power module
7. Power–up with the pulse and controller enable signals switched out

––> Observe the information/data in Chapter 4.10.1
––> Commission as described in Chapter 4.10.2
(up to and including Point 5.)
––> Check and set the rotor position identification
(refer to Chapter 4.10.2, Point 10.)
– P1016 (motor 1) = _ _ _ _ _ _ _ _ degrees electrical
Important:
For a Janus configuration (refer to Chapter 4.10.7) interchange
phases U and V.
