SFD Velocity Mode
The S200 can drive a brushless motor in Velocity Mode using SFD Feedback. The drive can be
configured either with the S200 tools over the serial port or configured using the S1 and S2
switches. Configuring the drive with the S200Tools utility provides increased flexibility in setting
parameters that are not available through the setup switches. When using the S200Tools utility,
the configuration parameters should be saved to non-volatile memory (click the NV Save
button) to allow the configuration to be recalled on power up.
To configure the drive for SFD feedback set the following parameters:
Parameter Value
CommMode
SetupS2-2 (Default value) with switch S2-2 set to the
down position labeled,
S
on the drive.
or
SFD
CommOff
0 Degrees – for AKM motor series. Check with your sales
representative for the correct commutation offset angle for
other motor series.
OpMode
Velocity
or
SetupS2-1 with switch S2-1 set to the up position labeled,
V
as shown on the drive.
SelSFDParam
SFD (Default value) – recommended setting
This setting automatically sets the motor parameters.
KVP
is set for 75 Hz nominal velocity loop bandwidth with
an unloaded motor.
To change
KVP
or other motor parameters, refer to
Configuring with SFD Feedback Motor Parameters.
ARF0
ARF1
Single pole filters in the velocity loop forward path. Set to
accommodate the effects of mechanical resonance
KVI
Sets the velocity loop break out frequency from integral to
proportional compensation.
CmdSrc
Selects Analog, PWM, or Command variable for
command.
CmdGain
Sets the command gain for the command input.
CmdOffset
Sets the command offset for the command input.
CmdF0
Sets the filtering on analog input command.
The following are optional parameters that can be set.
Parameter Function
EncOut
Sets the line count of the emulated encoder output.
EnInhibitCW
EnInhibitCCW
Enables the hardware over travel limits.
