Functions<br />
Below are the recommended brake control settings for vertical lifting<br />
applications (for a horizontal lifting application, set the current threshold to 0).<br />
Brake release current: Set the brake release current to the nominal current<br />
indicated on the motor. If torque is insufficient during testing, increase the<br />
brake release current (the drive imposes the maximum value).<br />
Acceleration time: For lifting applications, set the acceleration ramps to<br />
more than 0.5 s. Ensure that the drive does not change to current limiting.<br />
The same recommendation applies for deceleration.<br />
NOTE: For a lifting movement, a braking resistor must be used. Ensure<br />
that the settings and configurations selected cannot cause a drop or a loss<br />
of control of the lifted load.<br />
Brake release time delay: This is the time required for the mechanical<br />
brake to release. Adjust according to the type of brake.<br />
Brake engage frequency: Set to twice the nominal slip, then adjust<br />
based on the result.<br />
Brake engage time delay: This is the time required for the mechanical<br />
brake to engage. Adjust according to the type of brake.<br />
Limit switch management<br />
This function manages the operation of one or two limit switches (with one or<br />
two rotation directions).<br />
Each limit (forward or reverse) is associated with a logic input. The type of<br />
stop occurring on detection of a limit is configurable as normal, freewheel or<br />
fast.<br />
Following a stop, the motor can restart only in the opposite direction.<br />
