PARAMETERS
June 1999
96-8000
Parameter 198 SWITCH HYSTERESIS. UNIT:Hz.
This parameter is used when a Vector Drive is installed. This defines the + hysteresis band
around parameter 197. For example if par. 197 is 85 Hz, and par. 198 is 5Hz, the switching will
take place at 90Hz when the spindle is speeding up, and at 80 Hz when the spindle is slowing
down. If a Vector Drive is not installed, this parameter is called C axis ACCEL FEED
FORWARD, and is not used.
Parameter 199 PRE-SWITCH DELAY. UNIT: ms.
This parameter is used when a Vector Drive is installed. This is the amount of time allowed for
the current in the motor to drop before the winding change contactors are switched. If a Vector
Drive is not installed, this parameter is called C axis THERMAL COMP. COEF., and is not
used.
Parameter 200 POST- SWITCH DELAY. UNIT: ms
This parameter is used when a Vector Drive is installed. This is the amount of time allowed for
the contactors to stabilize after a switch is commanded, before current is applied to the motor.
If a Vector Drive is not installed, this parameter is called C axis AIR BRAKE DELAY, and is not
used.
Parameter 201 X SCREW COMP. COEF.
This is the coefficient of heating of the lead screw and is used to shorten the screw length.
Parameter 205 A SCREW COMP. COEF.
This parameter should be set to 0.
Parameter 206 SPIGOT POSITIONS
Vertical mills only. Maximum number of spigot positions.
Parameter 207 SPIGOT TIMEOUT (MS)
Vertical mills only. Maximum timeout allowed for spigot to traverse one spigot location.
Parameter 208 SPIN. FAN OFF DELAY
Delay for turning the spindle fan off after the spindle has been turned off.
Parameter 209 COMMON SWITCH 2
Parameter 209 is a collection of general purpose single bit flags used to turn some functions
on and off. The left and right cursor arrows are used to select the function being changed. All
values are 0 or 1 only. The function names are:
HORIZONTAL When set to (1), the control identifies the machine as a horizontal
mill. The control will then make the necessary adjustments, such as
enabling the horizontal tool changer.
RST STOPS T.C. Tool changer can be stopped with RESET button.
BRIDGE This bit should be set to 1 for the Bridge Mill, and 0 for all other
models.
M21-28 @ 540 When enabled (1), M21-28 is installed at cable 540.
ENA CONVEYOR Enables chip conveyor, if machine is so equipped.
