Basic Installation 3-1 MN1919
3.1 Introduction
You should read all the sections in
Basic Installation
to ensure safe installation.
This section describes the mechanical and electrical installation of the MicroFlex in the
following stages:
H
Location considerations
H
Mounting the MicroFlex
H
Connecting the AC power supply
H
Connecting the 24VDC control circuit supply
H
Connecting the motor
H
Installing a regeneration resistor (Dynamic Brake)
H
Connecting the feedback device
These stages should be read and followed in sequence.
3.1.1 Power sources
A 115 - 230VAC power source (IEC1010 over-voltage category III or less) in the installation
area is required. This may be single-phase or three-phase. An AC power filter is required to
comply with the CE directive for which the MicroFlex was tested (see section 3.4.7).
The 24VDC control circuit supply must be a regulated power supply with a continuous current
supply capability of 1A (4A power on surge).
3.1.2 Hardware requirements
The components you will need to complete the basic installation are:
H
The motor that will be connected to the MicroFlex.
H
A motor power cable.
H
An encoder feedback cable (and Hall cable for linear motors), or resolver cable.
H
A serial cable connected as shown in section 5.4.
H
(Optional) A regeneration resistor (Dynamic Brake) might be required, depending on the
application. Without the regeneration resistor, the drive may produce an overvoltage fault.
All MicroFlex models have overvoltage sensing circuitry. Regeneration resistors may be
purchased separately - see Appendix A.
H
A cooling fan may be required to allow operation of the MicroFlex at full rated current (see
section 3.2.2).
