(2) Rotary operation
The following describes rotary operation by positioning such as below a stepping motor.
: Angle of rotation per pulse (angle/pulse → deg/p)
: Rotary pulse coefficient, number of pulses per rotation (number of pulses/single motor rotation → p/rotation)
: Rotation pulse rate coefficient (number of pulses/single rotation of shaft → p/rotation)
m : Reduction gear ratio → number of teeth of gear A/number of teeth of gear B)
V
r
: Shaft rotation speed (number of rotations/sec → rps)
V
p
: Set pulse speed (speed to set to this module, number of pulses/sec → p/s)
R : Shaft rpm (rpm)
P
L
: Number of set travel pulses
The rotary pulse coefficient is calculated:
=360/ (number of pulses/rpm → p/rotation)
Vr
Shaft
Gear B
Gear A
Stepping motor
Thus, the pulse rate coefficient becomes:
= m=360×m/ (p/rotation)
Next, the pulse speed VP (speed to set to this module) when the table travel speed Vr (rps) is
generated from this coefficient:
V
P
=Vr =Vr×360×m/ (p/s)
The number of pulses (PL) for arriving at the set rpm is calculated as follows:
P
L
=R× =R×(360×m/ ) (p)
