Requirement Enter value here
a) Initial motor speed, before deceleration begins,
in radians per second.
Multiply RPM by 0.1047 to give radians per
second.
Initial motor speed:
U = _____________ rad/s
b) Final motor speed after deceleration is complete,
in radians per second.
Multiply RPM by 0.1047 to get radians per
second. This value will be zero if the load is
going to be stopped.
Final motor speed:
V = _____________ rad/s
c) The deceleration time from initial speed to final
speed, in seconds.
Decel time:
D = _____________ s
d) The total cycle time (i.e. how frequently the
process is repeated), in seconds.
See
Duty cycle

.
Cycle time:
C = _____________ s
e) Total inertia.
This is the total inertia seen by the drive,
accounting for motor inertia, load inertia and
gearing. Use the Mint WorkBench Autotune tool
to tune the motor, with the load attached, to
determine the value. This will be displayed in
kg·m
2
in the Autotune tool. If you already know
the motor inertia (from the motor spec.) and the
load inertia (by calculation) insert the total here.
