Explanation
DIR#
Selects/Deselects the quadrature
input circuitry. User has access
to up/down counter via OH1
command. The displayed rpm
is sent to the GPIB/RS-232 and
applied to the PID Loop.
NOTE: Only applies to DSP6001
Revision 7.5 and later versions.
Values for # are:
0 = for single frequency
1 = for quadrature input
I#
Sets current output to #.
The power supply outputs a fixed value of
current. Use any value # between 0 and
99.99%. (99.99% = 1 Amp).
IOXX.XX
Applies an offset to the output DAC
on channel 1 only. Used to clamp
motor speed prior to testing.
NOTE: Only applies to DSP6001
Revision 7.6 and later versions.
Values for # range from 0 to 99.99.
OH1
Returns quadrature counter
information.
Two 24-bit hex values are returned. The
first value is the up/down count. The
second value is an unused value.
SAVE
Saves present configuration of unit
to non-volatile memory.
X
Prompts to return % current output. This command returns the % current value
in the format “I##.##”. The value will be
between 0 (no loading) and 99.99 (full
loading).
