J3 EM Brake

P250 J3

Pin Name Description Typical Use
1 PWR Switched Battery Voltage EM Brake
2 Activator Open Drain brake drive signal EM Brake

J5 Control and Status I/O

P250 J5

Pin Name Description Typical Use
1 TPOTL TPOT Low: Low Potentiometer Reference Throttle potentiometer
2 CAN-H CANBUS High Signal Monitoring/Control
3 CAN-L CANBUS Low Signal Monitoring/Control
4 Switch 1 Configurable switch input
5 Driver 1 Open-Collector output
6 Switch 2 Configurable switch input Fault Input (Quickstop)
7 Driver 2 Open-Collector output Fault Output
8 N/C
9 N/C
10 TPOTH High Potentiometer Reference Throttle potentiometer
11 P5V P5V is a positive 5VDC regulated output which can be used to supply external circuitry. This output is current limit protected at approximately 30mA. Excitation voltage to hall-effect position sensors, or to throttle potentiometers
12 P15V P15V is a positive 15VDC unregulated output which is protected by a 235 ohm series source resistance. Excitation voltage to hall-effect position sensors
13 TPOTC Connects to the throttle potentiometer wiper Speed control
14 KEY_LOW Keyswitch active low. This is a digital input used to turn the MC unit on and off. This signal is asserted low, so the Controller will switch from off to on when this signal is pulled to GND. On/Off switch
15 ANIN Analog Input
16 ANOUT1 Auxiliary Output (0-5V)
17 ANOUT2 Auxiliary Output (0-5V)
18 I/O GND Ground reference for I/O Connections
19 POS_SENSE_C Motor Position sensor input C (W) Connected to motor sensor
20 POS_SENSE_B Position sensor input B (V) Connected to motor sensor
21 POS_SENSE_A Position sensor input A (U) Connected to motor sensor
22 KEY_HIGH Keyswitch input. This signal performs exactly the same function as KEY_LOW, but it is considered asserted when the signal level is > 2V On/Off switch. Alternately, see KEY_LOW
23 Switch 3 Configurable switch input Forward/Reverse selection
24 BATT Voltage supply at VBAT

Battery Connections

Use a properly-sized ring terminal to connect the battery leads.

Danger

Electrical charge may still be present on the battery connections even after the battery has been disconnected or power switched off. This stored charge will dissipate in a few minutes, but take care not to short the + terminal to a ground point because an electrical arc and possible damage to the controller may result.

Warning

Do not overtighten the terminal connections. Use a maximum torque of 20 inch-pounds. Overtightening may cause damage to the controller.

Motor Terminals

Use a properly-sized ring terminal to connect the motor leads to the M5 studs using the supplied nuts. For brushed motors, only two battery connections will be used (by default, connections U + W are used).

Warning

Do not overtighten the terminal connections. Torque to 20 inch-pounds. Overtightening may cause damage to the controller.
