8-8 Configuring Your 1394 Analog Servo System
[Cur Rate Lim]
The largest change in the current reference per
velocity loop sample that will be allowed is
specified through this parameter. Value shown
on the display is in amperes/millisecond.
Description is based on percentage of motor
rating to allow interpretation of value.
This parameter is automatically configured to its
maximum value when [Motor Type] (parameter
100) is changed.
[Current Limit]
This parameter automatically changes both
positive and negative current limits to the same
value (for convenience during commissioning).
[CW OvSpd Vel]
Clockwise trip velocity for an overspeed fault.
This value is automatically set to 1000 rpm
greater than [CCW Vel Lim] if this value would be
greater then present setting.
[CW Vel Lim]
Velocity mode clockwise maximum command
limit. This value is automatically set to the motor
rated velocity when the motor parameter is
changed.
[D/A #x Gain]
Scaling factor for the D/A output test point. For
maximum resolution, this parameter should be
set so Gain = 128/(Maximum D/A Value). Where
(Maximum D/A Value) is the largest value of the
parameter that is linked to [D/A Value]
(parameter 12). Important: Velocity is scaled for
4096 counts = 1000 rpm. Current (I
for 8192 counts = 100% motor rated current.
