Light Duty Dynamic Brake Resistor Operation
When the light duty dynamic brake resistor is applied, the braking operation
applies 100% duty cycle up to 10 seconds, followed by 3% duty cycle.
Standard Duty Dynamic Brake Resistor Operation
When the standard duty dynamic brake resistor is applied, the braking
operation applies 100% duty cycle up to 60 seconds, followed by 5% duty cycle.
Configure Electromechanical (EM) Brake
EM brake control can be automatic or manual. With automatic brake control,
the brake is released automatically when the motor control is started, and is
applied automatically when the motor control is stopped. EM Brake automatic
control is only available with Ramp Stop mode. With manual brake control,
you can release and engage the brake when needed, using a bit in an I/O
assembly (
DeviceName
:0.EMBrakeRelease is the output tag).
Choose a Release Mode for the EM Brake from the pull-down menu. If
choosing Automatic, also set the Off Delay and On Delay, see
Figure 80 - EM Brake Delay Timer Example
Click OK to exit the Stop Control page.

EM Brake Release Mode
Description
Always Engaged
The integrated EM brake contactor does not energize. Therefore, if the Armor
PowerFlex drive is connected to a motor with an EM brake, it never releases.
Automatic (default)
The EM brake releases once the Brake Off Delay timer is satisfied and it engages once
the Brake On Delay timer is satisfied (see
). When the delay is set to 0, the
brake releases once a valid start is detected by the drive and engages once a valid
stop condition has been detected. If Source Brake Release Mode is set to Automatic,
then the Stop Mode must be set to Ramp.
