5.2.1 - Resolution
This table displays the PTU-5 pan and tilt resolutions.
5.3 - User-Programmable Settings
The PTU has a number of user-programmable parameters that can significantly affect performance for a
given payload and application. These parameters should be set to values that are appropriate for your
payload and application needs. This section provides an overview of how to optimize your PTU for high-
power and/or high-speed operation. Please refer to the
Pan-Tilt E Series Command Reference Manual
for complete instructions.
5.3.1 - High-Speed Operation
The following factors should be considered when planning high speed operation:
• Load weight, weight distribution, and dynamics.
- Move the payload as close to the axis centers of rotation as possible. Doing this will reduce the
torque required to move the payload and allow a higher top speed.
- Balancing the load, such as by using a counterweight or splitting the payload into two pieces can
also help significantly.
• Desired upper speed limit.
• Rate of acceleration.
• The base (start-up) speed.
• Power supply voltage. Higher voltages within the permissible range significantly improve axis speed
and acceleration performance.
• In-motion power modes. If the duty cycle is less than 20%, you may use high move power to increase
the top speed.

CAUTION: USE HIGH-SPEED AND/OR HIGH-POWER SETTINGS WITH CARE,
PARTICULARLY WHEN MOUNTING A HEAVY AND/OR BULKY PAYLOAD.
WARNING: FAILURE TO ADEQUATELY SECURE THE PTU TO A MOUNTING THAT CAN
WITHSTAND THE FORCES APPLIED BY BOTH HIGH-SPEED, HIGH-POWER MOVEMENT
AND ENVIRONMENTAL FASCTORS SUCH AS VEHICLE MOVEMENT OR WIND CAN
CAUSE A STRUCTURAL FAILURE RESULTING IN INJURY OR DEATH.
