Motor ON/OFF Option The Motor ON/OFF option allows de-energizing a motor without disturbing the positioning logic. After reenergizing the motor, a routine can continue. This reduces motor heating and conserves power, especially in applications where motors are stopped for long periods and no holding torque is required. Motor Connections Hookup diagrams for a motor driver application are presented in Figure 3 and 4.
Dimensions Torque Speed Curves Torque curves are shown on the back of this specification sheet. This data was obtained using a high voltage (Vhv) of approximately 60VDC no load. The low voltage (Vlv) used was an unregulated voltage of about 5.5VDC no load. Both voltages dropped when loaded. To obtain more torque at high speeds, Vhv should be increased. To obtain more torque at standstill and low speeds, Vlv should be increased but the motor current at standstill should not exceed the motor’s rated current.

Specifications Control Inputs: TTL-CMOS Compatible Logic “0” = 0 to 0.8 VDC Logic “1” = 3.5 to 5.0 VDC Clock Inputs: (Terminals 5 & 6) Pulse required; 15 microseconds minimum. The clock input is pulled up internally to +5VDC through a 10K Ú resistor for negative going clock input, or pulled down to 0VDC through a 10K Ú resistor for positive going clock input.
