Function
Remarks
1
CREF+
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 the rated value.
4
ECLP
External current
limit – peak
External voltage scales down the rated value.
Voltage range: 0 V to 3.75 V (3.75V = rated Ip).
Internally limited to the rated value.
5
ECLRET
Current limits
return
Return for the current limit 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 the 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.
