4.3.3 Ramping Commands Description

The following MPS Ramping Commands configure the various functions of the ramping features.

RAMP Programs Ramp Segment Parameters

Input: RAMP[segment],[initial ramp current],[final ramp current],[ramp rate],[00],[--:--:--:--]

where:

[segment] = 1. (Future updates will allow up to nine segments.)

[initial ramp current] = 0 and ±50 A (620), 0 and ±125 A (622), 0 and ±155 A (623),

or 0 and ±72 A (647).

[final ramp current] = 0 and ±50 A (620), 0 and ±125 A (622), 0 and ±155 A (623), or

0 and ±72 A (647).

[ramp rate] = 0 to 99.9999 A/S.

[00]: Reserved for future use (Operation to perform). Need not be present for

proper command operation.

[--:--:--:--]: Reserved for future use (DWELL time in days, hours, minutes and

seconds). Does not need to be present for proper command operation.

Remarks: Truncates value to 0.001 place. Enter values with no embedded spaces. Undefined

parameters are set to 0. Control Bus inputs 4 places, display rounds to 0.01 or 0.001 place.

Example: RAMP1,+125.0000,-125.0000,01.0000[term]

Indicates: Ramp Segment = 1;

Initial Ramp Current = +125.0000 A;

Final Ramp Current = -125.0000 A;

Ramp Rate = 01.0000 A/S; commas can be replaced by blanks.

RAMP? Ramp Parameter Query

Input: RAMP?

Returned: Values are the same format as described above for programming in the ramp segments.

Remarks: Returns 48 characters and up to two terminators.

RMP Programs Ramp Status

Input: RMP [ramp status] where

[ramp status] = 0 to turn off (HOLD) the ramp definitely, or 1 to

turn on the ramp segment or continue a ramp on hold.

RMP? Ramp Status Query

Input: RMP?

Returned: 0 for holding, or 1 for ramping.

Remarks: One character plus up to two terminators are returned.

SEG Programs Active Ramp Segment

Input: SEG [segment] where [segment] = 1. (Future updates will allow multiple ramp segments).

SEG? Active Ramp Segment Query

Input: SEG?

Returned: 1. (Future updates will allow multiple ramp segments).

Remarks: Returns one character plus up to two terminator.
