Command
Description
PN
Sets the value of either the
minimum output voltage
allowed for an output, or the
minimum position voltage
expected for an input.·
Voltage settings are rounded to the nearest D/A or A/D code. Voltage settings
for Outputs are absolute levels and are unaffected by any software scaling
functions. Negative voltages are not valid for Input 3.
Syntax:
SEND_COMMAND
Variables:
I/O: Any input or output ('1','2','3','4','5','6','7','8')
LEVEL VALUE: -12.000V to +12.000V
Examples:
SEND_COMMAND
Sets the minimum output level for Output 1 to 5.023V.
SEND_COMMAND
Sets the minimum output level for Output 1 to -5.023V.
SEND_COMMAND
Sets the minimum of the expected input range for Input 7 to 5.023V.
PR
Sets the CURRENT
OUTPUT
TIME and/or CURRENT
OUTPUT
TIME of the specified Output
where TIME is the time to
ramp the full range.
It can be set to ramp both down to up and up to down or just down to up or just
up to down.
Syntax:
SEND_COMMAND
Variables:
OUTPUT: Any Output '1', '2', '3', or '4'
TIME: 0 - 255 in 0.1 second increments
U/D: Ramp Up (U) or Down (D)
Examples:
SEND_COMMAND
Sets CURRENT OUTPUT 1 RAMP UP TIME" and "CURRENT OUTPUT 1
RAMP DOWN TIME" to 2.5 seconds each for full range travel.
SEND_COMMAND
Sets CURRENT OUTPUT 2 RAMP UP TIME to 7.5 seconds for full range
travel, CURRENT OUTPUT 2 RAMP DOWN TIME remains unchanged.
SEND_COMMAND
Sets "CURRENT OUTPUT 2 RAMP DOWN TIME" to 5 seconds for full range
travel; "CURRENT OUTPUT 2 RAMP UP TIME" remains unchanged.
PU
Sets the level to which this
Output is set immediately
after power-up and before
any Output is commanded.
Syntax:
SEND_COMMAND
Variables:
OUTPUT: Any Output ('1', '2', '3', or '4')
LEVEL VALUE: 0-255
Example:
SEND_COMMAND
Sets the power up output level for Output 1 to 127.
