3.6.1.2. J1 Connector

Pin #/

Short Form

Function Remarks

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

CREF-

Current command input ( - ) Negative input of a differential amplifier.

Specification as for pin J1/1.

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

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

ECLRET

Current limits return Return for current limits signals.

Current monitor

Analog output with a scale of ±3.9 V for ±Ip.

• Output resistance: 10 kΩ

CMRET

Current monitor return Return for current monitor (CM) signal.

CGC

Current gain change Shorting this pin to the CGCRET pin (J1/9)

reduces the proportional gain (P) of the

current loop by 70%.

CGCRET

Current gain change return Return for CGC signal.

CFM

Current feedback multiplier Shorting this pin to pin J1/8 (CGC) multiplies

the current feedback signal by 2.
