Heatsink mounted braking resistor

A resistor has been especially designed to be mounted within the
heatsink of the Unidrive 6 (sizes 1 and 2).The design of the
resistor is such that no thermal protection circuit is required, as the
device will fail safely under fault conditions.On Unidrive 6 sizes 1
and 2, the in built software overload protection is set up at default for
the designated heatsink mounted resistor. If an external brake resistor
is used, a thermal over load device is required, refer to User Guide.

NOTE The heatsink mounted resistor is suitable for applications with

a low level of regen energy only.

WARNING

For complete
wiring and fusing
instructions, refer to the
Unidrive 6 User Guide

*

Thermal overload for
external braking resistor
to protect against fire
risk.This must be wired
to interr upt the AC
supply in event of a fault

Autotune

Unidrive 6 is able to perform either a stationar y or a rotating
autotune.The motor must be at a standstill before an autotune is
enabled.A rotating autotune should be used whenever possible.

•

A stationar y autotune can be used when the motor is loaded
and it is not possible to remove the load from the motor
shaft.A stationary autotune does not measure the power
factor of the motor so the value on the motor nameplate
must be entered into Pr 0.43

•

A rotating autotune should only be used if the motor is
unloaded or the load is uncoupled

To perform an autotune:

•

Set Pr 0.40 = 1 for a stationar y autotune or set Pr 0.40 = 2
for a rotating autotune

•

Close the Drive Enable signal (terminal 31).The dr ive will
display ’rdY’

•

Close the run signal (ter minal 26 or 27).The lower display will
flash ’Auto’ and ’tunE’ alternatively, while the drive is
performing the autotune

•

Wait for the drive to display ’rdY’and for the motor to come

to a standstill

Remove the run signal from the drive.

Run

•

Drive is now ready to run

WARNING:A rotating autotune will cause the motor to

accelerate up to 2/3 base speed in the direction

selected regardless of the reference provided.Once

complete the motor will coast to a stop. The r un
signal must be removed before the drive can be made to run at
the required reference.The drive can be stopped at any time by

removing the run signal or removing the drive enable.
