Step Modes; Configuring Step Mode - FLIR PTU-D300 User Manual

COMMAND REFERENCE
The following command sets the host serial port RS232/RS485 to a baud rate
of 19,200 bits/second (8 data bits per byte, no parity, no handshaking), a
30ms delay between bytes output from the pan-tilt controller, and the power
up baud rate overrides the default and is set at 19,200 baud.

4.8 Step Modes

4.8.1 Configuring Step Mode

Description
The default motion resolution of the D300 controller is half step mode.
Firmware versions 2.12.8 and higher added microstepping in quarter and
eighth steps. Microstepping provides much quieter operation and smoother
motion at slow speeds. In addition, the microstepping increases the effective
resolution of the pan-tilt unit.
The controller will automatically select the correct step mode based on the
pan-tilt's current speed, and process all units as though the unit were in eighth
step mode while allowing the unit to move at the higher speeds of half step.
Syntax
W<axis><resolution> where
for
resolution.
Example
The following command puts the tilt axis into eighth step resolution and
recalibrates the tilt axis, which returns success (*).

Known Issues
• Autostep mode is only supported in firmware versions v2.13.0 and higher.
This firmware supports querying the microstep mode with the
"W<axis><delimiter>" command.
• Microstepping decreases the pull-out torque of the motor.

Firmware versions 2.13.0 and higher added autostep electronic gearing.
