Ramping State Commands and Queries
• CONFigure:RAMPDown:RATE:FIELD <segment>,<rate (kG/s, kG/min,
T/s, T/min)>, <upper bound (Kg, T)>
Sets the external rampdown rate for the specified segment (values of 1
through the defined number of rampdown segments are valid) in units of
kilogauss/second or minute, or tesla/second or minute (per the selected
field units and rampdown rate units), and defines the field upper bound for
that segment in kilogauss or tesla. This command requires that a coil
constant be defined; otherwise, an error is generated.
• RAMPDown:RATE:FIELD: <segment>?
Returns the external rampdown rate setting for the specified segment
(values of 1 through the defined number of rampdown segments are valid)
in units of kilogauss/second or minute, or tesla/second or minute (per the
selected field units and rampdown rate units) and the current upper bound
for that range in kilogauss or tesla (per the selected field units). This
command requires that a coil constant has been defined; otherwise, an
error is generated. The two return values are separated by a comma. For
example:
RAMPDown:RATE:FIELD:1?
0.0100,5.0000
4.5.6 Ramping State Commands and Queries
The ramping state commands control and query the ramping state of the
Model 430 Programmer. For more information regarding each state, see
section 3.12.
If the ramping state is commanded remotely, the front panel display and
LED indicators will update and accurately reflect the commanded ramping
state.
• RAMP
Places the Model 430 Programmer in automatic ramping mode. The Model
430 will continue to ramp at the configured ramp rate(s) until the target
field/current is achieved.
• PAUSE
Pauses the Model 430 Programmer at the present operating field/current.
• INCR
Places the Model 430 Programmer in the MANUAL UP ramping mode.
Ramping continues at the ramp rate until the Current Limit is achieved.
