6 ENERGIZING AND START OF OPERATION
This chapter explains:
How to check and prepare the servo drive before energizing it.
How to energize and check the success of the energizing.
How to program the servo drive according to the servomotor used in the application by using the guided
Start-Up routine.
6.1 PREPARATION AND ENERGIZING
The servo drive must be already installed according to
chapter 3 INSTALLATION AND CONNECTION on page
3-1
. If the drive project is different from the typical suggested drives, the following steps may also be followed.
DANGER!
Always disconnect the main power supply before performing any servo drive connection.
DANGER!
Débranchez toujours l'alimentation principale avant d'effectuer une connexion sur le Entraînement
d'asservissement.
1. Check if the power, grounding and control connections are correct and tight.
2. Measure the network voltage and check if it is within the permitted range, as described in
section 9.1 POWER
DATA on page 9-1
.
3. Measure the 24 Vdc supply voltage which supplies the control and check if it is within the permitted range, as
described in
section 9.2 ELECTRONICS/GENERAL DATA on page 9-2
.
4. Mechanically uncouple the servomotor from the load:
If the servomotor cannot be uncoupled, it must be ensured the spinning in any direction (clockwise or counter
clockwise) will not cause damages to the machine or risk of accident.
5. Energize the control:
The HMI must display P00000.
6. Energize the power:
Close the input disconnecting switch.
The red LED “Power on” must turn on.
6.2 PROGRAMMING AND OPERATION
The SCA06, besides its basic function of servo drive, features two additional functions: PLC and Motion Controller,
which are accessible via programming in ladder language in a personal computer using the appropriate WEG
programming software
(1)
.
The servo drive can be controlled by an external device (such as a CNC, for instance) via analog/digital inputs/
outputs or via communication networks (CANopen network, for instance). It may also be operated independently
by using its PLC/Motion Controller functions via ladder programming.
The way of operation of the servo drive is defined primarily by the parameter P00202:
