4. [ OPERATION ]
4.1 Pre-commissioning
When you are convinced that your application’s linear motor system is
assembled in a proper way, both mechanically and electrically, you can
proceed to the next step. You can put your motor system into operation.
But before powering the system, please do have a final check:
1.
Does the slide have a free run over the whole
magnet track, without touching small mechanical
parts like bolts or contamination?
2.
Are the mechanical end stops, end switches and
the dampers well dimensioned and properly
configured?
3.
Does your system have an emergency stop?
4.
When used, is the temperature cable properly
connected?
5.
Does the motor ruler combination have the right
polarization?
6.
Has the power cable been connected properly?
7.
Does the physical earth has been connected properly?
4.2 Configuring
After the amplifier is powered up some input and output signals need to
be examined.
1.
Check the end switches by pushing the slide manually to the
switch position. Simultaneously check whether the signal is
detected by the amplifier.
2.
Check the presence of the PTC signal.
3.
The following motor items should be configured as parameter
settings of the servo amplifier:
■
Maximum continuous current.
■
Maximum peak current.
■
Amount of coils.
■
Maximum speed.
■
Presence/absence of an electromechanical motor brake.
■
Magnet interval (North-South distance) and/or pole pitch
(North-North distance).
■
Switching resistance of PTC.
4.
The following settings for the ruler system should be configured
as parameters of the servo amplifier:
■
Type of interface of the ruler system.
■
Resolution or period of the linear encoder.
5.
These are the I/O parameters to be configured:
■
Settings of the available digital inputs and outputs. For instance,
■
pay attention to the type of end switches.
■
Settings of the available analog inputs and outputs.
6.
Finally the controlling parameters must be configured.
■
Current control settings. These settings depend on both motor
and amplifier.
■
Speed control settings.
■
Position control settings.
