Response Message; Table 4-4. Structure Of The Poll Command Message - Advanced Energy Pinnacle 20 kW Manual

Advanced Energy
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.

RESPONSE MESSAGE

The following table represents the structure of the response message.

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 reached
• TS stands for Temperature Status: 1 = good; 0 = over-temperature condition
• ARCD stands for Arc Detected: 1 = on; 0 = off
• INTS stands for Interlock Status: 1 = satisfied; 0 = open
Scaling
Parts of the Message structure are based on binary representation of analog voltages. Thus
they have analog scaling associated with them.
The scaling for power output is 0 to 10 V, where 10 V = the full rated output power capability
of the Pinnacle power system (master and slave units). The read back is limited to 10 V
(0FFF ), even in those cases where output may temporarily exceed the maximum output
hex
capability of the power system.
