Basic Installation 3-1MN1902
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 FlexDrive
II
in the
following stages:
H Location considerations
H Mounting the FlexDrive
II
H Connecting the AC power supply
H Connecting the optional customer supplied 24VDC control supply
H Connecting the motor
H Installing a regeneration resistor (Dynamic Brake resistor)
H Connecting the feedback device
H Connecting the drive enable input.
These stages should be read and followed in sequence.
3.1.1 Power sources
An AC power source (IEC1010 over-voltage category III or less) in the installation area is
required. This will need to be single or three- phase depending upon the type of FlexDrive
II
.
An AC power filter is required to comply with the CE directive for which the FlexDrive
II
was
tested (see section 3.4.5).
If the FlexDrive
II
requires an external (customer supplied) 24VDC logic supply then this must
be a regulated power supply with a continuous current supply capability of 1.75A (4A power on
surge). A 24V filter may be required to comply with the CE directive for which the FlexDrive
II
was tested (see section 3.4.5).
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 FlexDrive
II
H A motor power cable
H A resolver or encoder feedback cable (and Hall cable for linear motors)
H With some applications there may be a requirement for a regeneration resistor (Dynamic
Brake).
Note: Without the regeneration resistor, the drive may produce an overvoltage fault. All
FlexDrive
II
models have overvoltage sensing circuitry , but only 2.5A and 5A
models (catalog numbers FDHxxxxxB-xxxx and FPHxxxxxB-xxxx) have an
internal regeneration resistor. For 7.5A, 15A, 20A and 27.5A models a
regeneration resistor must be purchased separately if required. See Appendix A.
