9. Installation and commissioning
9.1 Introduction
The following description shows the procedure for commissioning a ser-
vodrive with the PCD2.H3.. motion control module. To guarantee fault-
free operation of the H3 module, during commissioning the steps de-
scribed below should be executed in the same sequence.
Selection criteria for a servo-drive with the PCD2.H3.. module
A motion control unit always comprises the following parts:
•
A motion controller for setting the motion control parameters (position,
velocity and acceleration) and for position control. This task is per-
formed by the PCD1/2 with the H3 module.
•
A servo-amplifier for triggering the servomotor.
•
A servomotor for converting electrical into mechanical energy.
•
A position transmitter, in the form of an incremental shaft encoder.
•
A mechanical drive unit.
Selection of servo-amplifier and servomotor:
Regardless of whether a DC or AC servodrive is used, special attention
should be paid to the following points.
•
Amplifier and motor must match each other (power, voltage and cur-
rent).
•
For precise position and speed control, a four-quadrant power output
stage is required with integral speed governor.
•
The greatest possible governing range for amplifier and motor speed,
so that the necessary torque can be applied even at low speeds.
•
The H3 module supplies an analogue
±
10V signal as the speed set-
point.
•
For position capture, the H3 module needs an incremental shaft en-
coder that supplies at least two square-wave signals in phase quadra-
ture.
