Air Flow
We strongly recommend that brake/exhaust duct is
fitted to the drive whether a brake is fitted or not. It is
important that the top vent is properly fitted to assure
that the exhaust air is not recirculated.
We also recommend that these drives are separated
from other equipment in a large multifunction cabinet
so that the airflow is better controlled. i.e. air heated by
other items should not affect the inlet temperature to
the drive’s main fan.
The volumetric airflow rate for each drive is:
G = 583m3/hr (343CFM) H = 1505m3/hr (884CFM) J = 1753m3/hr (1032CFM).
WARNING!
This unit must be operated with either a brake unit or blanking plate fitted to the
supplied outlet duct. The top vent is then mounted on to the outlet duct. It is very
important that the gasket for the vent is correctly fitted to the brake/exhaust outlet duct.
Otherwise, hot exhaust air will flow back into the cabinet and overheat the drive. The
brake/exhaust outlet duct should protrude from the top of the cabinet by 5-10mm to ensure
engagement with the gasket. Refer to Chapter 4: Installation Drawings in the Engineering
Reference manual for more information

AC Line Choke
IMPORTANT The drive must be used with an AC Line Choke, however, where a drive is
individually supplied from a dedicated transformer with the required
impedance, the AC Line Choke is not required.
We can supply the line chokes listed in the Engineering Reference Manual, Appendix E: "Technical
Specifications" - Line Chokes.
If you wish to source your own line choke refer to the individual Electrical Rating tables in Appendix E
for the relevant rms line currents. For constant torque applications refer to the AC Line Choke table for
the peak instantaneous line current under overload conditions.
Caution
Failure to provide the correct line impedance will severely reduce the drives lifetime and could result in
catastrophic failure of the drive.
Main Cooling Fan and Supply Requirements
The Frame G and H drives have an integral main cooling fan.
However, the Frame J drive has a separate main cooling fan which must be fitted to the bottom panel
of the enclosure with the 4 off M6 nuts provided as shown in drawing HG465731U001 at the end of
Chapter 4 in the Engineering Reference Manual. Also refer to drawing HG463151D002 for fan wiring
details (Frame J only) in Chapter 10: “Routine Maintenance and Repair” – Fan Replacement.
The drives require an external single phase supply and fuse protection (motor start type) for the main
cooling fan.

Incremental Pulse Encoders
The default settings for the drive are for 2048 line,
quadrature, incremental pulse encoders with differential
outputs operating from a 10VDC supply.
•Z channel (Marker pulse) connections are not
necessary for running the drive, but inputs are
provided for positioning and servo applications. The
supply voltage to the encoder is set in the Quick
Setup menu. Range 10 VDC to 20 VDC
Use the Keypad to set the following options:
Supply Voltage - PULSE ENC VOLTS
Number of lines per revolution - ENCODER LINES parameter
* Encoder direction - ENCODER INVERT
* Used to match the encoder direction to the motor direction. When TRUE, changes the sign of the
measured speed and the direction of the position count. It is necessary to set up this parameter when
in CLOSED-LOOP VEC mode, as the encoder direction must be correct for this mode to operate.
Using other types of encoders requires the 890 DSE Configuration Tool and the setting of other
parameters. Refer to the 890 Engineering Reference Manual for details of these parameters.
This section is only for closed loop vector and induction servo applications.
Skip this page if there is no encoder or resolver mounted on the motor.
