Motor Controller 29 276-2193 The VEX Motor Controller 29 uses a standard PWM signal (like that originating from the 3-wire ports on VEX Microcontrollers) to drive a VEX 2-Wire Motor. Note:We recommend using no more more than one (1) 3-Wire extension cable in between the Motor Controller 29 and a VEX Microcontroller. For longer extensions, use 2-Wire extension cables in between the Motor Controller 29 and a VEX 2-Wire motor. Compatible with 3-wire motor ports on all VEX Microcontrollers Inputs Black Wire - Ground Orange Wire - Power White Wire - PWM Signal: 1ms - 2ms will give full reverse to full forward, 1.5ms is neutral Max Battery Voltage:Max battery voltage: 8.5V (with fully charged 7.2V battery) Max Current:Max current: 4 A
