4.0 Commissioning
DANGER
During and after operation, some parts of the cylinder carry
dangerous voltages. Electric shock hazard. Risk of serious
or fatal injuries.
Strictly observe the safety instructions in this manual and
the safety instructions of manuals associated with each
commissioned equipment (motor, servoamplifier, etc).
Do not unplug motor connectors before switching off the power
supply of the corresponding servoamplifier. First unplug the
signal connector and then the power connector.
Motor rotation can create voltage. Do not touch connector pins.
WARNING
During operation, the cylinder surface temperature can reach
high values. There’s a risk of burns or fire. Before any work on
the actuator, let it cool down.
4.1 Overview
DANGER
Customer should make sure that the commissioning steps
suggested in the general procedure can’t create any
problems.
The described procedure assumes that mechanical and
electrical installation have been done correctly.
NOTE
Actuator is greased supplied.
To perform the very first commissioning of a cylinder, the
general principle is as follows:
1. On the computer, ensure installation of the software re-
quired for defining servoamplifier parameters – installa-
tion of hardware connection between computer and
servoamplifier.
2. Switch on the servoamplifier (only auxiliary supply or
low-level supply) to allow servoamplifier parameters
definition.
3. Launch the software required for servoamplifier parame-
ters definition. Operation checking of connection be-
tween computer and servoamplifier.
4. Definition of servoamplifier parameters. At the very least,
the following information has to be entered:
4.1. Cylinder motor choice (if necessary, choice of re-
solver or encoder associated) and associated brake
choice if necessary.
4.2. Fill in the following data:
4.2.1. Cylinder move for each motor revolution
(⮑ 2.2 Operating principle for definition).
4.2.2. Cylinder speed defined for application.
4.2.3. Cylinder acceleration defined for application.
4.2.4. Definition of starting control parameters (see
servo-amplifier’s technical documentation).
4.3. Save modifications in non-volatile memory.
NOTE
Before going on to step 5, please check that the para-meters
given in steps 1–4 have been correctly saved in the non-volatile
memory. To do that, switch off and on the servo-amplifier. Then
check that the parameter modifications have been correctly
taken into account in the servoamplifier.
5. Switch on the power supply of the servoamplifier. Check
the cylinder motor brake operation (for example: when
the cylinder motor torque comes on, a brake clap has to
be heard. Same thing when the cylinder motor torque
turns off).
6. Make a small cylinder move (smaller than overstroke
value which is written on cylinder drawing) in a positive
direction to see the actual direction of pushing tube
move (please read the end of paragraph 3.3.3.1
Description (of limit switches) to know how positive di-
rection is defined). Generally, the pushing tube extends
when a positive move is ordered. Otherwise, please re-
verse the motor rotation direction.
7. Check the limit switch in the retracted position by moving
the cylinder slowly and gradually to that position.
8. Check the limit switch in the extended position by mov-
ing the cylinder slowly and gradually to that position.
9. If a home switch has been installed, check its operation
by moving the cylinder slowly and gradually to a position
where the home switch status changes.
10. Make a program for defining the zero reference and
check that this program works correctly, whatever the
cylinder starting position (⮑ 4.3 How to define zero
reference before beginning to make a program,
page 25).
11. Measure the two extreme positions (pushing the tube in
the extended position and in the retracted position)
within which the cylinder could move without activating
the limit switches (these two positions will be defined in
relation with zero reference defined just above).
