CME2 Default Setting for Brake Outputs [OUT6,7] is “Brake - Active HI”
Active = Brake is holding motor shaft (i.e. the
Brake is Active)
Motor cannot move
No current flows in coil of brake
CME2 I/O line States shows Output 6 or 7 as HI
BRk output voltage is Hi (24V), MoSFet is oFF
Servo drive output current is zero
Servo drive is disabled, PWM outputs are off
Inactive = Brake is not holding motor shaft (i.e. the
Brake is Inactive)
Motor can move
Current flows in coil of brake
CME2 I/O line States shows Output 6 or 7 as lO
BRk output voltage is lo (~0V), MoSFet is on
Servo drive is enabled, PWM outputs are on
Servo drive output current is flowing
The brake circuits are optically isolated from
all drive circuits and frame ground.
This diagram shows the
connections to the drive that
share a common ground in
the driver. If the brake 24V
power supply is separate
from the DC supply powering
the drive, it is important
that it connects to an earth
or common grounding point
with the hV power supply.
*
There should be only one
conductor in each position of the
J5 connector. If brakes are to be
wired directly to J5 for their 24V
power, use a double wire ferrule
for J5-4. Information for ferrules
can be found on page 27.
