Power Wiring – Sizes 3 to 9A
Heatsink mounted braking resistor
A resistor has been especially designed to mount within the heatsink of
the Unidrive M sizes 3, 4 & 5. 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 M sizes 3, 4 & 5 the software overload
protection is set up at default for the designated heatsink mounted
resistor. If an external brake resistor is used, a thermal overload device is
required. 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 M Power
Installation guide.
*Thermal overload
for braking resistor to
protect against fire risk.
This must be wired to
interrupt the AC supply
in the even of a fault.
This is not required if
the optional heatsink
mounted braking
resistor is used.

Keypad & Display
By default, the keypad display is in “Status Mode” for viewing current
drive conditions, and can be changed to “Parameter Mode” for viewing
and editing drive configuration settings.
Status mode
When in status mode, the drive status message/alarm/trip code is
displayed on the upper left corner of the upper line, i.e., “Ready”,
“Inhibit”, “Trip”. See the “Display Messages” topic for more details.
Parameter mode
When in parameter mode, drive functionality can be viewed or modified
by using the keypad. The parameter number is displayed on the upper line
of the display (ex, 00.010), the parameter description is displayed on the
second line, and the parameter value is displayed on the right-hand side
of the bottom line.
Viewing parameters
The parameter number format is S.MM.PPP, where S = slot number
for option modules and built-in communications, MM = menu number
(menus are groupings of common functions), and PPP = parameter
number (parameters are specific drive functions). For example: Pr. 00.010
is menu 0, parameter 10. Note: Menu 0 contains the most common
parameters used in a typical setup and is programmable.
Upper line
Displays the parameter
number, drive status, or
drive trip code.

Keypad & Display
Navigating menus and parameters
You can find any parameter value using the arrow buttons. The and
buttons are used to navigate between the slots and menus. The and
buttons are used to navigate between the parameters in a menu.
To edit/modify parameters
In order to change the value of a parameter, go to the parameter you
would like to change and then press the enter button. Now the cursor
shifts to the parameter value. You can increase the parameter value by
pressing the up button or decrease the parameter value by pressing the
down button. The right and left buttons can be used to switch between
the digits within the parameter value. Pressing the enter button again will
set the newly selected parameter value, and the cursor will return to the
parameter number.
Note: Certain parameters are read only (RO) and cannot be changed. For
example Pr. 0.11– drive output frequency, cannot be changed. Pressing
the return button will return the keypad to status.
To Save parameter values
Changes made to parameters will be lost when the drive is turned off
unless parameters are saved. To save new parameter changes, enter 1001
into any Pr.MM.000 and then press the Stop/Reset button.
To reset to USA (60 Hz) defaults
To reset the drive to USA default parameter settings, open the drive
enable signal (Terminal 31), enter 1244 into Pr MM.000 and then press
the Stop/Reset button. Save the parameter values by entering 1001 into
Pr MM.000 and then pressing the Stop/Reset button.

Alarm string Description
Brake resistor Brake resistor overload. Braking resistor thermal accumulator (10.039) in the drive has
reached 75.0% of the value at which the drive will trip.
Motor overload Motor protection accumulator (04.019) in the drive has reached 75.0% of the value at
which the drive will trip and the load on the drive is >100%.
Inductor overload Regen inductor overload. Inductor protection accumulator (04.019) in the drive has
reached 75.0% of the value at which the drive will trip and the load on the drive is
>100%.
Drive overload Drive over temperature. Percentage of drive thermal trip level (07.036) in the drive is
greater than 90%.
Autotune The autotune procedure has been initialized and an autotune in progress.
Limit switch Limit switch active. Indicates that a limit switch is active and that is causing the motor
to be stopped.
Display Description - troubleshooting tips
Over volts • Increase deceleration ramp (Pr 00.004).
• Decrease the braking resistor value (staying above the minimum value).
• Check nominal AC supply level.
OI.AC • Acceleration/deceleration rate is too short.
• If seen during auto-tune reduce the voltage boost.
• Check for short circuit on the output cabling.
Encoder2 • Ensure that the position feedback device type selected in Pr 03.038 is correct for the
position feedback device connected to the P1 interface on the drive.
• If wire break detection on the drive encoder input is not required, set Pr 03.040 =
XXX0 to disable the encoder 2 trip.
• Check cable continuity.
• Check wiring of feedback signals is correct.
• Check encoder power supply is set correctly (Pr 03.036).
Status indications
For other display messages and trip codes with more recommended actions please refer to the
Unidrive M700/M701/M702 Control User Guide or to the mobile Diagnostic Tool app.
Display Description
Inhibit The drive is inhibited and cannot be run.
Ready The drive is ready to run.
Stop The drive is stopped/holding zero speed.
