2.7: SYSTEM CLAMP
The system clamp allows the processor to energize or de-energize the motors by toggling a
1/0 bit. Any time a motor is moved, the 1/0 bit “system ready” must be enabled. This
allows step data to be converted to motor current. Therefore, anytime “system ready” is
enabled, motors are either stepped by changing step data, or clamped by unchanging step
data present at the input of the amplifier. “System ready” also enables the printwire driver
circuit.
