Control Commands
Acceleration in Milliseconds
Command:
A <nnnn>
Description:
Acceleration setting for variable speed devices. The number nnnn represents the time in
milliseconds for the positioner to reach max speed. For high inertial loads, a longer acceleration
time might be required.
Query:
A?
Returns:
The time in milliseconds for the positioner to reach max speed.
Example:
AXIS1:A 1000
Acceleration in Seconds
Command:
ACC nn.n
Description:
Acceleration setting for variable speed devices. The number N.N represents the time in seconds
for the positioner to reach max speed. For high inertial loads, a longer acceleration time might
be required.
Query:
ACC?
Returns:
The time in seconds for the positioner to reach max speed.
Example:
AXIS2:ACC .5
Homing Procedure
Command:
HOME
Description:
The device has a mechanical home sensor. Every time the positioner is turned on, a home
procedure must be performed so the current position is known by the firmware.
To home the positioner, send the following commands:
HOME
*OPC?
Keep querying the positioner by sending the *OPC? until it returns 1.
*OPC? Will return 0 if the turntable is still being homed.
*OPC? will return 1 if the home procedure is done.
After *OPC returns 1, send the query HOME? to confirm that the positioner found the
mechanical home sensor.
HOME? returns 0 if the home procedure was not successful; result of a faulty sensor.
Query:
HOME?
Returns:
1 if the AXIS1 has been homed, 0 otherwise
Example:
AXIS1:HOME
Lower Limit
Command:
LL nnn.n
Description:
Sets the lower/counterclockwise limit of the device. The specified value nnn.n must be less than
the upper/clockwise limit.
Query:
LL?
Returns:
Lower or counterclockwise limit of the device in degrees.
Example:
AXIS1-2:LL 0,-10
