SPD DEV TIME
(Speed Deviation Time) This parameter
defines the time the speed feedback
needs to be in the range around the
speed reference defined by SPD DEV LO
LEVEL (A1) before the Speed Deviation
Low logic output is true.

SPD DEV HI
LEVEL
(Speed Deviation High Level) Level for
declaring speed deviation alarm. Units
are in percent of contract speed. See
SPD DEV LO LEVEL and SPD DEV HI
LEVEL on page 49.

subtracts an effective voltage to the

300% or the value in CURRENT LIMIT
(A1). For more information, see Analog
Inputs on page 27 and Pre-Torque /

EXT TORQUE
MULT
(External Torque Multiplier)
This
parameter scales the analog pretorque /
torque command (channel 2). If this
function is set to 1.00, a 10V signal will
call for 100% torque. Note: Drive
automatically limits current at 300% or
the value in CURRENT LIMIT (A1). For
more information, see Analog Inputs on

PRE TORQUE
TIME
(Pre Torque Time)
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.
