PARAMETERS
June 1999
96-8000
Parameter 189 C BASE FREQ
This parameter is used when a Vector Drive is installed.This is the rated
frequency of the motor. If a Vector Drive is not installed, this parameter is called C axis DEAD
ZONE, and is not used.
Parameter 190 C HI SP CURR LIM
This parameter is used when a Vector Drive is installed. At speeds higher than the base
frequency, the maximum current that is applied to the motor must be reduced. This is done
linearly from base frequency to max frequency. this value is the max current at the max
frquncy. If a Vector Drive is not installed, this parameter is called C axis IN POSITION LIMIT,
and is not used.
Parameter 191 C MAX CURRENT
Same definition as Parameter 105.
Parameter 192 C MAG CURRENT
This parameter is used when a Vector Drive is installed. This is the magnetization component
of the current in the motor, also called the flux or field current. If a Vector Drive is not installed,
this parameter is called C axis D*D GAIN, and is not used.
Parameter 193 C SPIN ORIENT MARGIN
This parameter is used when a Vector Drive is installed. When a spindle
orientation is done, if the actual position of the spindle is within this value (plus or minus), the
spindle will be considered locked. Otherwise, the spindle will not be locked.If a Vector Drive is
not installed, this parameter is called C axis ACC / DEC T CONST, and is not used.
Parameter 194 SPINDLE STOP FREQ
This parameter is used when a Vector Drive is installed. The spindle is considered to be
stopped (discrete input SP ST*=0) when the speed drops below this value. Units are encoder
steps/millisecond. If a Vector Drive is not installed, this parameter is called C axis PHASE
OFFSET, and is not used.
Parameter 195 C START/STOP DELAY
This parameter is used when a Vector Drive is installed. This delay is used at the start of
motion to magnetize the rotor before acceleration starts. When the motor comes to a stop it
remains energized for this amount of time. Units are in milliseconds. If a Vector Drive is not
installed, this parameter is called C axis GRID OFFSET, and is not used.
Parameter 196 C ACCEL LIMIT LOAD
This parameter is used when a Vector Drive is installed. This is the % load limit during
acceleration. If the load reaches this limit during acceleration the control slows down the
acceleration. If a Vector Drive is not installed, this parameter is called C axis EXACT STOP
DISTANCE, and is not used.
Parameter 197 SWITCH FREQUENCY.Unit:Hz.
This parameter is used when a Vector Drive is installed. This is the frequency at which the
spindle motor windings are switched. Note that there is a hysteresis band around this point,
defined by parameter 198. If a Vector Drive is not installed, this parameter is called C axis
FRICTION FACTOR, and is not used.
