GND (Pin 9)
The GND pin (Pin 9) is the return path for + 5 Vdc (Pin 10) input/output pin. It is also common
connection for External, Analog or PWM Control Methods. Pin 9 (Gnd), is common to the (Gnd)
terminal of the power supply connector. Use isolated input signals as required to avoid ground
loop issues.
+5 Vdc (Pin 10) (Input)
In this section, pin 10 is described as an externally supplied input. If you selected the
internally generated output, see the section below.
Voltage Input Range: 4.75 to 5.25 Vdc
Current Input: power supply must provide a minimum of 56 mA
The +5 Vdc input is externally supplied by the end user depending on the GreenDrive
TM
option
selected.
The +5 Vdc input provides power for internal electronics. The user su5 Vdc input is
critical to the performance of the motor control. Care and attention must be taken not to deviate
away from voltage specifications to prevent potential harm to the motor control system.
