4.6 Increasing the Maximum Speed
The maximum speed of the actuator being driven is dependent upon the phase
current settings. The unit is shipped with default settings suitable for the majority of
applications, and for the ZST series of actuators these settings will deliver a max
speed of around 250 µm depending on load.
For applications which require a higher max speed the ‘Moving Phase Current’
settings must be increased. This is achieved via the APTUser utility ‘Settings’ panel,
please see Section 6.3.3. for more details.
Warning
The default values applied by the software have been selected based on
the type of stage or actuator connected and are applied automatically on
start up.
Modify these values with caution as the risk of damage to the motor due
to overheating is significant. For the Thorlabs ZST series actuators, the
moving phase power is set to 60% at the factory. This is appropriate for
velocities of 0 to 250 µm/s. If higher speeds are required, this value can
be increased up to 80% but this could result in serious overheating if the
motor is then moved at low speeds.
The homing velocity should not be increased from 250 µm/s factory
setting as this may damage the limit switches.
