AKM Installation | 7 Technical Data
Note 2: Maximum Release Voltage - value of voltage where the brake is 100% OPEN.The brake is mounted
inside of the motor.
Note 3: Minimum Re-Engage Voltage - value of voltage where the brake is 100% CLOSED. The brake is moun-
ted inside of the motor.
Note 4: Backlash - amount of clearance, or free rotation, from a point based in one direction to a point in the
opposite direction with torque applied, between the drive connection of the brake to the motor shaft. 25% of the
rated torque of the brake can be applied during the backlash measurement.
Note 5: Maximum Backlash is calculated using worst-case tolerancing, and typical backlash is calculated using
statistical tolerancing.
Note 6: Release and response times measured on standalone brakes with Kollmorgen AKD drive. Release/Re-
sponse 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 con-
tains 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 AKM 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.
Note 15: 'B10d' and 'Number of Springs' is specific to AKM motors with brakes that are labeled 'Made in Czech
Republic'. Please contact Kollmorgen for all other inquiries.
