Spindl I Gain
The velocity loop integral gain used in the spindle mode is set with this
parameter. This data is programmed in Per Unit Torque / Per Unit
Velocity Error/second or % Torque / % Velocity Error / second. The units
for this parameter are 1/seconds.

Data Range:

1/S 00.00 to 50.00

Default Value

00.20

Speed Cal
This parameter allows exact matching of the speed command to the actual
motor speed. When an analog input equal to the maximum spindle speed
command is supplied from the CNC, the Scroll keys can be used to adjust
the motor speed until the displayed actual speed matches the commanded
speed. Press the Select key to store the setting.

This could be considered a fine tuning of the Max Cmnd Spd parameter.
As the appropriate Scroll key is pressed, a multiplier factor for the Max
Cmnd Spd
parameter is incremented in 0.04% steps. There is a time delay
of approximately one second after the multiplier is changed until it can be
observed in the system operation. During this operation, the display is
operating as a digital speed meter showing current motor speed.
Reprogramming the Max Cmnd Spd parameter will reset this multiplier to
zero.

Data Range:

RPM 00000 to 30000

Default Value

0.00%

SERVO MODE
This menu selects the various setup and tuning procedures needed to set the
operating parameters that are used when the Spindle/Servo Mode Select
input is On.

Analog In #
Analog In # determines which analog input is going to be used for the
velocity command in servo mode. If the drive is to operate in torque
mode, Analog Input #1 must be used for the velocity command.

Possible Choices: INPUT #2, INPUT #1
Default Value

INPUT #2
