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.
Parameter Numbers 192, 193, 194, 195
Parameter Group Torq Data
Display Units A/ms
Parameter Type Read/Write
Change While Running Ye s
Linkable No
Minimum Value 10% rated motor current/ms
Maximum Value 100% rated motor current/ms
Default Value 100% rated motor current/ms
[Current Limit]
This parameter automatically changes both
positive and negative current limits to the same
value (for convenience during commissioning).
Parameter Numbers 116, 117, 118, 119
Parameter Group Startup Parms
Display Units amps
Parameter Type Read/Write
Change While Running Ye s
Linkable No
Minimum Value 10% rated motor current
Maximum Value 300% rated motor current
Default Value 10% rated motor current
[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.
Parameter Numbers 152, 153, 154, 155
Parameter Group Vel Cmd Data
Display Units rpm
Parameter Type Read/Write
Change While Running Ye s
Linkable No
Minimum Value 0 rpm
Maximum Value 8000.0 rpm
Default Value This is determined by the motor catalog number.
[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.
Parameter Numbers 128, 129, 130, 131
Parameter Group Vel Cmd Data
Display Units rpm
Parameter Type Read/Write
Change While Running Ye s
Linkable No
Minimum Value 0.0 rpm
Maximum Value 8000.0 rpm
Default Value This is determined by the motor catalog number.
[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
Q
) is scaled
for 8192 counts = 100% motor rated current.
Parameter Numbers 10, 11
Parameter Group Setup
Display Units None
Parameter Type Read/Write
Change While Running Ye s
Linkable No
Minimum Value -2.0000
Maximum Value +2.0000
Default Value 0.0000
