Functional description

  • The start frequency for binary control mode and RS485 control mode is 2 Hz. If the function is not activated, the start frequency is 0.5 Hz.
  • The brake release time is fixed to 200 ms (default = 0 ms). This prevents the motor from working against the applied brake.
  • The brake application time (post-magnetization time) is fixed to 200 ms. This setting ensures that the brake is applied as soon as the motor stops generating torque.
  • The K1 relay is assigned the "Brake released" function.
  • When relay K1 is open, the brake brakes the motor.
  • When relay K1 is closed, the brake is released.

Overview of brake control with additional function 9 (control via RS485 + binary control):

Brake application time (post-magnetization time)

[2]

Premagnetization time

Frequency

[3]

Brake control signal "1" = released, "0" = applied

[7]

Stop frequency = start/minimum frequency

[4]

Brake release time

Mechanical brake is controlled by the relay output or the BEM/BES option.

WARNING

Risk of crushing due to unintentional startup of the drive caused by incorrect settings of the DIP switches S2/5 – S2/8. Failure to comply with chapter Use of the relay output for additional functions 7, 9, 12, and 13 can result in the brakes releasing.
Severe or fatal injuries.
  • A braking resistor (BW..) must be connected to terminals X1:13 and X1:15 in the MOVIMOT® connection box. Terminal X1:14 is not assigned.
  • Relay K1 acts as brake control relay. This means that the ready signal function is no longer available.

INFORMATION

In hoist operation, the "Release brake without enable" function is not effective.
