Response Message - Advanced Energy Pinnacle User Manual

Advanced Energy
• 2.5 V = 0.25 x power output setpoint per second
• 0 V = No ramping rate specified; the Pinnacle unit ramps as fast as it can
If you request a ramping-to-setpoint value that exceeds 10 V, the setpoint will be
limited to the equivalent of 10 V.
Ramping
The Pinnacle unit examines the ramping-to-setpoint rate only if the output power
setpoint has been set to a new value. Ramping will begin again at 0 after an off-on
sequence has occurred.

Note: The 16-bit Power Output value (AI) is shifted right four bits, and the remaining
four bits are filled with 0s. This changes the 16-bit AI to a 12-bit AI with a
value of 10 V = OFFF
Note: For Byte 8, the abbreviations have the following meanings:
• POS stands for Power On Status: 1 = output on; 0 = output off
• SPS stands for Setpoint Status: 1 = setpoint reached; 0 = setpoint not
• TS stands for Temperature Status: 1 = good; 0 = over-temperature
• ARCD stands for Arc Detected: 1 = on; 0 = off
• INTS stands for Interlock Status: 1 = satisfied; 0 = open
