AKM2G Instructions | 7 Technical Data
Note 6: Release and response times measured on standalone brakes with Kollmorgen AKD drive.
Release/Response Time of the brake measured with a diode and a transistor in power supply circuit.
Note 7: Brake release time, i.e. the time for the brake to release when the power is applied to the brake, is fairly
consistent regardless of how the brake is switched.
Note 8: Brake response time, i.e. the time taken for the brake to re-engage when the power is cut if the circuit
contains any form of arc suppression over the switching, then the decay circuit within the brake, when the power
is cut, will be prolonged.
Note 9: Cutting the brake supply on the 'dc' side, i.e. a clean cut in the brake supply at the brake connection, will
give the fastest possible switching.
Note 10: Current of the brake is calculated from nominal voltage and nominal resistance at 25°C
Note 11: Acceleration calculated from maximum acceleration of Kollmorgen AKM2G motor with the brake
without external load.
Note 12: Brake is able to perform 50.000.000 reverse cycles with maximum acceleration and backlash up to
0.8°.
Note 13: B is number of operations where 10% of the sample would fail to danger.
10d
Note 14: New brake - brake mounted in the motor without previous usage. Parameters could be influenced by
number of emergency stops absorbed by brake during lifetime.
