Gearmotor has drive and encoder built in

The type 34B4/FV-F INTEGRAmotor gearmotor combines a brushless dc motor, a high-torque gearhead, a PWM speed control, and an optical encoder. The motor provides 1/4 hp (187 W) and up to 341 lb-in. (39 Nm) continuous torque and is stocked in gear ratios of 5:1 to 180:1 with rated output speeds of 0.3 to 500 rpm. It operates from 24 Vdc.

The drive’s 1,024-PPR two-channel optical encoder provides closed-loop feedback to an external setpoint in velocity or position control mode. Inputs include PWM voltage control, amplifier enable, direction, and dynamic braking. There is a fault signal output and a current limit to protect the motor from short-term overload.
