[A155]
(Speed Zero Band) Voltage range that is
considered to be a zero speed command
when analog speed commands are used.
Typical value less than 50 mV. Can be
determined by shorting to/- analog
speed command inputs and view results in
ANALOG SPD CMD (D1).

Pre Torque
Time
i,ii
[A158]
(Pre Torque Time
i,ii
)
Time to ramp torque
from zero to pre-torque value. When set to
zero, Pre-Torque will be applied
immediately. This helps eliminate the
‘bump’ felt upon starting caused by the
torque being immediately set to rated pre-
torque. Setting this parameter to zero will
disable the Pre Torque Ramp Up function.
With a non-zero setting for Pre Torque Time,
the torque reference will be linearly ramped
from zero to the value given through the
Analog Input Channel or the serial channel.

This

is set to 1.00, a 10V signal will call for 100%
torque. For more information, see Analog
