Power Specifications Brake Override Input
The brake override connection is made on two dedicated pins of the hybrid input
connector. The hybrid cable has no connection on those pins.
The brake override may only be activated when the hybrid input cable is not
connected. A brake override cable is attached at the location where the hybrid
input cable would normally be attached.
Two connections are required for the motor/brake override input power.
Connections are rated for +24V and current as shown in the table below. An
active signal releases the motor brake.

ATTENTION: To guard against personal injury and/or component damage, the
brake override must only be used for machine assembly when the IPIM module
is not connected to the IDM unit.

Term Definition
(1)
(1) All current values are specified as rms.
Continuous Current Rating (I
Cont
) The maximum value of current that can be output continuously.
Peak Current Rating (I
PKmax
) The maximum value of peak current that the drive can output. This rating is
valid only for overload times less than T
PKmax
.
Duty Cycle (D) The ratio of time at peak to the Application Period and is defined as:
Time at Peak (T
PK
) The time at peak current (I
PK
) for a given loading profile. Must be less than or
equal to T
PKmax
.
Peak Current (I
PK
) The level of peak current for a given loading profile. I
PK
must be less than or
equal to the Peak Current Rating (T
PKMAX
) of the drive.
Base Current (I
Base
) The level of current between the pulses of peak current for a given loading
profile. I
Base
must be less than or equal to the continuous current rating (I
Cont)
of the drive.
Loading Profile The loading profile is comprised of I
PK
, I
Base
, T
PK
, and D (or T) values and
completely specify the operation of the drive in an overload situation. These
values are collectively defined as the Loading Profile of the drive.
Application Period (T) The sum of the times at I
PK
(T
PK
) and I
Base
.
D = T
T
PK x 100%
