RAMP(OPCSDEFS) Optical Printer Control System RAMP(OPCSDEFS) NAME ramp - configure motor's maximum acclerations and velocities USAGE ramp [chan] [norm accel] [norm vel] [slew accel] [slew vel] EXAMPLES Velocities ___|____ | | --- --- ramp a 10 150 15 200 ramp a 10 150 15 200 -- -- ------ ------ |_______| | | | | Slewing speed Accelerations | Normal speed DESCRIPTION This command sets up the maximum accelerations and velocities. Since the kuper card works at 120 samples per second, the values represent the number of pulses per sample, or the number of pulses per 1/120th of a second. Acceleration values are used for ramping. As the motor comes up to speed, it will do so in increments specified by the 'acceleration'. Velocity values are the maximum running velocities. The motor will not go faster than the maximum velocity supplied.
