*The module uses its motor power circuits to decelerate the motor per the Accel/Decel DIP Switch settings. Once the motor has finished its controlled deceleration, then it applies one of these 3 Electronic Holding Brake options in which to provide various levels of holding brake force or resistance. The Electronic Holding Brake function IS NOT used to slow down the motor
Electronic Holding Brake Definitions
| Method |
Description |
| Normal |
Standard Dynamic Shunt Coil – Each of the 3 Motor power transistor circuits in the are internally shunted to ground after the module has performed its configured deceleration function. The mechanical inertia of the gearbox and the magnetic resistance of the motor rotor provides the holding force. This is the MDR industry standard holding braking method |
| Free |
Free Spin – Each of the 3 Motor power transistor circuits in the are internally opened after the module has performed is configured deceleration function. The mechanical inertia of the gearbox provides the only holding force |
| Servo Brake |
Active Servo – When the module has performed is configured deceleration function, it remembers the position of the motor rotor and provides active power to the motor coils to maintain that roller position |

Mechanical Holding Brake Option
Some Pulseroller MDR’s and PGD’s are available with an option for a mechanical holding brake. Please note this is separate and not related to the Electronic Holding Brake functionality.
!Please note that ONLY EZ-QUBE-HTBF-P, -N models provide release control for a mechanical holding brake
!For EZ-QUBE-HTBF-P, -N DO NOT use Servo Electronic Brake Method when you have a mechanical holding brake because this may overheat and damage the MDR or PDG unit.
