The limitation is effective for the following activities:
● Jog mode
● Processing traversing blocks
● Direct setpoint specification / MDI for positioning and setting up
● Reference point approach
● Stop responses due to alarms
Jerk limitation is not active when messages are generated with stop responses OFF1 / OFF2
/ OFF3.
Starting against a closed brake
Under EPOS, if the drive should start against a closed brake, for example, for a suspended
load, then the enable signal p0899.2 is briefly withdrawn. The drive pulses are canceled and
fault F07490 is output.
To avoid this happening, using p1513 activate a supplementary torque which corresponds to
the brake holding torque. As a result, after releasing the brake, the load cannot sag and the
drive remains in closed-loop control without fault F07490 being output.
