TERMINAL FUNCTIONS LEVELS
NOTES:
1. When Forward Run and Reverse Run inputs are both closed for more than 500 ms, the Digital
Operator flashes “
EF ” and the motor (if rotating) is decelerated by the GPD 503 to a stop. This stop
condition is not stored by the GPD 503 (on Digital Operator, red lamp at STOP key does not light);
IF ONE OF THE INPUTS IS OPENED, THE MOTOR WILL IMMEDIATELY START UP
AGAIN.
2. Terminals 1-8 source +24 Vdc and operate in a Low = True (ON) configuration when connected to
terminal 11.
When using relays for input to terminals 1-8, use relays with highly reliable contacts (for very small
current) with a capacity of 30 Vdc or more and rated current of 100mA or higher. When using
transistor (open collector) input, use transistors with rated voltage of 35 Vdc or more and rated
current of 100mA or more.

1.4.3 Grounding
• The GPD 503 must be solidly grounded using main circuit ground terminal G (E).
Ground resistance should be 100 ohms or less. Select lead size suitable for size
of terminal screw. Make the length as short as possible.
• NEVER ground the GPD 503 in common with welding machines, motors, or
other large-current electrical equipment.
• Where several GPD 503s are used, ground each directly or daisy-chain to the
ground pole(s). DO NOT FORM A LOOP WITH THE GROUND LEADS.
