Terminology
It will be necessary to be familiar with some terms used in
this document.
Connector
Slider
MNS direction PLS direction
Motor
bps bit per second; the unit of communication speed.
closed logic output state; output current will flow.
Driver Unit means Megathrust Motor System’s driver unit when capitalized.
Home Return
a built-in sequence program for setting the home position.
kpps kilo pulse per second; the unit of pulse frequency.
MNS direction of Motor motion, minus (negative); see figure above.
Motor means Megathrust Motor System’s motor when capitalized.
OFF (all capital) logic input state; input will see an open circuit.
ON (all capital) logic input state; there will be a current path to the common DC supply.
open logic output state; no output current
P control proportional-only control; the servo algorithm.
PI control proportional and integral control; the servo algorithm.
PLS
direction of Motor motion, plus (positive); see figure above.
position gain shorter name for position loop proportional gain
position integrator frequency shorter name for position loop integrator cutoff frequency
position loop control mode a control mode within the position control loop; P control or PI control available.
Programmable Indexer Driver Unit’s built-in indexing ability.
pulse train a series of pulses used as a position command.
quadrature output two pulse train outputs with 90° phase difference.
rated stall force
the rated force available at zero speed.
rated force the force not to exceed the maximum Motor winding temperature.
servo-lock
one typical state of servo-on; the Motor provides force and remains in position.
servo-off the state where the Driver Unit provides no current to the Motor, and the Motor
provides no force. The Motor slider can be moved easily.
servo-on the state that the Driver Unit is ready to control the Motor, or is controlling the Motor.
shipping set a parameter setting or a Driver Unit function setting at shipping.
stall force the force available at zero speed.
System means Megathrust Motor System when capitalized.
velocity gain
shorter name for velocity loop proportional gain
velocity integrator frequency shorter name for velocity loop integrator cutoff frequency
velocity loop control mode a control mode within the velocity control loop; P control or PI control available.
