3.6.1.2. J1 Connector
Pin #/
Short Form Function Remarks
1
CREF1+ Current command input ( + ) Positive input of a differential amplifier:
•
Input operating voltage range: ±3.75 V
• Maximum input voltage: ±20 V, see
Section 4.1
• Maximum common mode voltage: ±6 V
(referred to as CMRET)
• Differential input impedance: 40 kΩ
2
CREF- Current command input ( - ) Negative input of a differential amplifier.
Specification as for pin J1/1.
3
ECLC External current limit- continuous External voltage scales down the rated value.
• Voltage range: 0 V to 3.75 V (3.75 V =
rated Ic)
• Internally limited to rated value
4
ECLP External current limit - peak External voltage scales down the rated value.
•
Voltage range: 0 V to 3.75 V (3.75 V =
rated Ip)
• Internally limited to rated value
5
ECLRET Current limits return Return for current limits signals.
6
CM Current monitor Analog output with a scale of ±3.9 V for ±Ip.
•
Output resistance: 10 kΩ
7
CMRET Current monitor return Return for current monitor (CM) signal.
8
CGC Current gain change Shorting this pin to the CGCRET pin (J1/9)
reduces the proportional gain (P) of the
current loop by 70%.
9
CGCRET Current gain change return Return for CGC signal.
10
CFM Current feedback multiplier Shorting this pin to pin J1/8 (CGC) multiplies
the current feedback signal by 2.
