MOTOR PHASE CONNECTIONS<br />
MOTOR ENCODER (OPTIONAL)<br />
<strong>Stepnet</strong> <strong>Panel</strong><br />
The drive output is a dual H-bridge that converts the DC buss voltage (+HV) into sinusoidal<br />
voltage waveforms that drive the motor phases. Cable should be sized for the continuous<br />
current rating of the drive. Motor cabling should use twisted, shiel<strong>de</strong>d conductors for CE<br />
compliance, and to minimize PWM noise coupling into other circuits.<br />
Six <strong>de</strong>dicated inputs accept the enco<strong>de</strong>r A, B, and X (in<strong>de</strong>x) signals. Enco<strong>de</strong>rs with differential<br />
line-drive outputs must be used.<br />
MOTOR BRAKE (OPTIONAL)<br />
Digital outputs [OUT1,2,3,4] can be programmed to power a motor-mounted brake. These<br />
brake the motor when they are in an unpowered state and must have power applied to<br />
release. This provi<strong>de</strong>s a fail-safe function that prevents motor motion if the system is in an<br />
unpowered (uncontrolled) state. Because brakes are inductive loads, an external flyback<br />
dio<strong>de</strong> must be used to control the coil voltage when power is removed. The timing of the<br />
brake is programmable.<br />
MOTOR TEMPERATURE SENSOR (OPTIONAL)<br />
Digital input [IN5] is programmable for use with a motor overtemperature switch. The<br />
input should be programmed as a pull-up to +5 Vdc if the motor switch is groun<strong>de</strong>d.<br />

MOTOR CONNECTIONS<br />
The only motor connections required for stepper operation are the motor phases. These carry the drive output currents that drive the<br />
motor to produce motion. The feedback enco<strong>de</strong>r, brake, and motor over-temperature sensors are optional. If stall-<strong>de</strong>tection is <strong>de</strong>sired<br />
in stepper operation the enco<strong>de</strong>r is required. When operating a stepper as a servo-motor the enco<strong>de</strong>r is also required.<br />
