Product manual

Danaher Motion 05/2008 Advanced Configuration
S200-VTS Product Manual 85
See AuxFBDivisor to complete the setup of the Aux Feedback interface.
Note: Many EnDat 2.2 devices can be wired to the J14 AuxFB Connector as long as the 1 Vp-p
Sin-Cos analog signals are also wired and the device will run in EnDat 2.1 compatibility mode.
Power up initialization of absolute position will work.
BatFDis Enable/Disable
This parameter enables or disables the Battery Low fault. The Battery input on the command
I/O connector is an optional feature and is not required for proper operation of the drive. It is
only required if the battery backup of the multi-turn information is required from the SFD. If the
feedback device is not an SFD, then the battery does nothing.
0 - Enable Battery Fault
1 - Disable Battery Fault
CmdF0 1.518 – 93254 Hz
CmdF0 sets the break frequency in Hz for two cascaded single pole low pass filters on the
hardware command input. There are two ranges of values for CmdF0; from 2915 to 24873 Hz
cannot be set. The lower range is the active range suggested for velocity control and the upper
range is used to effectively turn the filter off for velocity control or for use with torque/current
control. This parameter is particularly useful when CmdSrc selects the PWM input for the
command source. CmdF0 should be less than the input PWM frequency divided by 10 and
preferably divided by 50 or more. See the
Base Drive Torque/Velocity Control Block Diagram
for more information.
CmdGain See Chart
CmdGain sets the scale factor from the user input on the Command I/O connector (J4) to the
internal servo loop command. CmdGain can be negative or positive, which allows the direction
polarity to be changed. Because the input to the command processing block can be an analog
voltage or a digital duty cycle and the servo loop could be Torque/Current or velocity there are
four combinations of units listed below. See CmdSrc and OpMode for these settings. See
CmdOffset for adding an offset to the command.
Expressed as an equation:
CmdIn = [(User Input) – CmdOffset] * CmdGain
NOTE: The Range of CmdGain is clipped by the value of CmdOffset. The chart below gives
CmdGain units and numerical range assuming that CmdOffset is 0 V/50%.
CmdSrc OpMode CmdGain Units +/- CmdGain Range
Analog Torque / Current ARMS / V ARMS / V
Analog Velocity krpm / V krpm / V
PWM Torque / Current ARMS / % ARMS / %
PWM Velocity krpm / % krpm / %
CmdInNullEnb Enable/Disable
CmdInNullEnb enables or disables the Command In ADC Null function. CmdInNullEnb enabled
allows the user to null the base drive CmdIn ADC by asserting DInp4 for a minimum of one
second. The CmdInNull function will update the variable CmdOffset to null out the DC offset
that is present and the CmdIn ADC at the time DInp4 is asserted. This function updates the
drive NV memory copy of CmdOffset as well.
0 - Enable CmdIn ADC Null function
1 - Disable CmdIn ADC Null function (default setting)
CmdOffset Volts or Percent
CmdOffset is added to the user input on the Command I/O connector J4 to allow any constant
offset present in the source to be cancelled. Because the input to the command processing
block can be an analog voltage or a digital duty cycle, there are two possible units. See
CmdSrc for this setting and CmdGain for scaling the gain of the input command.
Expressed as an equation:
CmdIn = [(User Input) – CmdOffset] * CmdGain
