Checking whether DynaStop® can be used
Requirement:
To use DynaStop®, the retrodriving torque Mar must be smaller than the maximum deceleration torque MDSP:
Calculating the retrodriving torque:
Known values of the application:
Fex = 800 N
FR = 445 N
Motor type | MDSP (torque at the motor shaft) Nm | nDSP (speed at the motor shaft) min-1 |
---|---|---|
CM3C80S../D.. | 8.24 | 136.82 |
CM3C80M../D.. | 10.01 | 96.04 |
Result:
The application uses a K37 CM3C80S/D.. with the assigned inverter 2.0 A and a gear unit ratio itot = 37.97.
The maximum deceleration torque MDSP at the motor shaft speed nDSP for this design can be found in the product manual > chapter "Technical data" > "DynaStop® torques".
This allows for checking to see if the retrodriving torque Mar at the gear unit output side is lower than the maximum deceleration torque MDSP (also calculated at the gear unit output side):
DynaStop® can be used if this condition is met.
