Gecko 320/340 Interface Connector Pinout

Connectors :

J1 is the connector to the Gecko axis 1.
J2 is the connector to the Gecko axis 2.
J3 is the connector to the Gecko axis 3.
J4 is the connector to the Gecko axis 4.
Pin # Signal
1 Gecko Enc -
2 Err/Res
3 Phase B
4 Phase A
5 Enc +

J5 provides the encoder signals to the computer. For each axis, the encoder signals are A and B. Pins are as follows :
Pin # Signal
1 + 5 V supply
2 Gnd
3 Axis 1 Phase A
4 Axis 1 Phase B
5 Axis 2 Phase A
6 Axis 2 Phase B
7 Axis 3 Phase A
8 Axis 3 Phase B
9 Axis 4 Phase A
10 Axis 4 Phase B
11 ground to enable
12 not used

J6 sends the fault condition to the computer. It is an opto-coupler output, and can be used to either pull to +5 V or ground as needed. It passes current when no Gecko is in the fault condition. Pins are as follows :
Pin # Signal
1 +
2 -

J7 handles power to the Gecko drives. When enabled by pin 11 of J5, power flows from the DC supply to the Gecko drives. Any power returned from the motors to the Gecko drives is allowed to flow to the capacitors in the power supply. When disabled, the power supply is disconnected, and a braking resistor on the Gecko interface drains away any power flowing from the motors, and safely brakes them to a stop. Pins are as follows :
Pin # Signal
1 DC Power Supply
2 Power to gecko drives
3 Power Supply Ground
