GFK-3169C
Notes:
Note 1: Minimum Dry Static Torque - max. torque that can be applied to a brake without the risk of
slipping.
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
mounted 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 connected to hard switching
power supply.
Note 7: Brake release time, the time for the brake to release when the power is applied to the brake, is
consistent regardless of how the brake is switched.
Note 8: Brake response time, the time taken for the brake to engage when the power is removed and
circuit contains any form of arc suppression, is increased.
Note 9: Removing the DC voltage to the brake by a clean cut in the brake supply at the brake
connection, will pro- duce the fastest possible brake engagement.
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 Emerson IC830M 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
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 IC830M motors with brakes that are labeled
'Made in Czech Republic'. Please contact Emerson for all other inquiries.
Note 16: Please contact Emerson for detailed specification and all other inquiries.
Note 17: Response times measured on standalone brakes connected to Emerson PSD drive. Response
time of the brake measured with a diode and a transistor in power supply circuit.
Note 18: Total time needed to achieve 90% of static torque (see graphs below). Vertical load application
setup requires using the PSD or alternative drive manufacturers total torque rise time.
