Parameter Description - Basic Set Up
a) Input coded set speed selection LF.02 = d SPd
(Default setting)
b) Analog Torque control LF.02 = A tor
d SPd d SPd d SPd
d SPd
Digital speed setting uses preset digital values in the drive as
command speeds. The drive creates the driving profile between
selected speeds.

The differential analog signals are connected to the terminals
X2A1(+) and X2A2(-) and X2A3(+) and X2A4(-). The actual
torque command is the sum of the differential inputs.
Torque command = (X2A1 - X2A2) + (X2A3 - X2A4)
In a torque controlled system the maximum speed is
controlled by the elevator control not the drive. However
for safety reasons the drive will internally limit the speed
to 110% of LF.20 or contract speed.
Terminal X2A.14.5 is used to activate the starting and
stopping routine. The directions below must be followed in
the exact sequence they are listed:
