5. Ramp To Hold is selected by setting [Stop Select x]. The drive will ramp the
frequency to zero based on the deceleration time programmed into [Decel
Time 1/2]. Once the drive reaches zero hertz, a DC Injection holding current
is applied to the motor. The level of current is set in [DC Brake Level].
In this mode, the braking is applied Continuously. [DC Hold Time] has no
effect in this mode. Braking will continue until one of the following events
occur:
– The Enable Input is opened, or . . .
– A Start command is re-issued.
Again, caution must be exercised to not overheat the motor by applying excess
voltage and/or for excess time, particularly if the motor is not rotating.
