Function Explanation
Communications H Sets hi
g
h data acquisition
rate (120 samples per
second)
The Controller outputs data at 120 S/s (Usin
g
an
RS-232 interface, the rate is 60 S/s.) Use this
command durin
g
the ramp up/down when a short
test time is required.
Communications L Sets low data acquisition
rate (3.8 samples per
second)
The Controller outputs data at 3.8 S/s (default
rate).
Communications OA Prompts to return to
auxiliary input data strin
g
"Output Auxiliary" prompt to return the value at
the AUX INPUT x AUX SCALING factor.
Communications OD Prompts to return speed-
torque-direction data strin
g
"Output Data" prompt to return data strin
g
with
this format:
SxxxxxTxxxxxRcrlf or SxxxxxTxxxxxLcrlf
R or L is the shaft direction indicator, as viewed
lookin
g
at the dynamometer shaft, where:
R = ri
g
ht; clockwise (CW)
L = left; counterclockwise (CCW)
The speed will equal the displayed value and the
torque will be in the same units as displayed on
the front panel.
Ramp PD# Sets ramp down rate to
#RPM per second
Specify a speed ran
g
e (A, B, C, D, E, F#) AND
a stop speed (S#) before usin
g
this command.
This command pro
g
rams a decreasin
g
shaft
speed at a rate of #RPM per second. Once
initiated, the Controller will load to locked rotor
unless instructed to do otherwise.
Ramp PR • Resets ramp up or down
• Sets speed to max.
speed
• Turns brake off
This command resets the ramp function, haltin
g
the ramp's pro
g
ress, and returns the motor to
free-run.
Ramp PU# Sets ramp up rate to #RPM
per second
Specify a speed ran
g
e (A, B, C, D, E, F#) AND
a start speed (S#) before usin
g
this command.
This command increases the shaft speed at a
rate of #RPM per second.
Ramp S# Sets start or stop speed for
ramp to #RPM
When this command is used with the PD
(Pro
g
ram Down) command, the Controller will
ramp down to this speed and halt.
When this command is used with the PU
(Pro
g
ram Up) command, the Controller will load
immediately to this speed and ramp up to free-
run.
Setup M1 Enables front panel controls Use this command to enable front panel control
of most functions.
Setup M0 Locks out front panel
controls
Use this command to lock out the front panel
controls, so that the Controller settin
g
s can be
chan
g
ed only by usin
g
the computer with either
the GPIB (IEEE-488) or the RS-232 interface.
Note: The brake ON/OFF switch on the front
panel still functions.
