8-180Trio BASIC Commands
Axis Parameters
Trio Motion Technology
Example:
A leadscrew arrangement has a 5mm pitch and a 1000 pulse/rev encoder. The units
should be set to allow moves to be specified in mm. The 1000 pulses/rev will gener-
ate 1000 x 4=4000 edges/rev. One rev is equal to 5mm therefore there are 4000/
5=800 edges/mm so:
>>UNITS=1000*4/5
Example 2:
A stepper motor has 180 pulses/rev and is being used with
MICROSTEP=OFF
To program in revolutions the unit conversion factor will be:
>>UNITS=180*16
Note:
Users with stepper axes should also read the
MICROSTEP
command when choosing
UNITS
.
VERIFY
Type:
Axis Parameter
Description:
The verify axis parameter is used to select different modes of operation on a step-
per encoder axis.
VERIFY=OFF
Encoder count circuit is connected to the
STEP
and
DIRECTION
hardware signals so
that these are counted as if they were encoder signals. This is particularly useful for
registration as the registration circuit can therefore function on a stepper axis.
VERIFY=ON
Encoder circuit is connected to external A,B, Z signal
Note:
On the MC202 and the Euro205 when
VERIFY=OFF
, the encoder counting circuit is
configured to accept
STEP
and
DIRECTION
signals hard wired to the encoder A and B
inputs. If
VERIFY=ON
, the encoder circuit is configured for the usual quadrature
input.
Take care that the encoder inputs do not exceed 5 volts.
