Pulse frequencies
The switching times of the brake depend on many factors, such as the operating temperature of the brake, the degree of wear, and the tolerances of the components used. The set braking torque is a particularly decisive factor influencing the switching times.
The following table gives us guide values for the following switching times:
- Response time t1,I for standard excitation
- When operated with the BMS.. and BS24 brake control units, or with direct DC supply without a brake control unit
- Response time t1,II for high-speed excitation
- When operated with the BME.., BMP.., BMK.., BMKB.., BMH.., BSG.., or BMV.., as well as BG1Z and BS1Z. brake controls.
- Application time t2,I with pure cut-off in the AC circuit (AC)
- Application time t2,II with cut-off in the AC and DC circuit (AC/DC) or disconnection only in the DC circuit (DC)

Comments:
For BP.., BK.. and BKB.. as well as BR.D, BY.D, and BZ.D brakes, the opening time for high-speed excitation and the application time for AC shutdown are not defined due to their operation as a 2-wire brake with DC 24 V.
For the BR.., BY.., and BZ.. brakes, the opening times for standard excitation are not defined because these are operated with controls for fast excitation.
For the BY.C brake, opening is performed by the motor controller of the DRC. Since, as a current controller, the DRC motor controller performs an overexcitation, this mode is by definition considered high-speed excitation. In this sense, the application time is interpreted as a DC shutdown.
The times stated are guide values that were determined with the brake at operating temperature. These may vary under real application conditions.
