What is MC2 curve?
The MC2 curve has a constant velocity in movement the same
as the MC (modified constant velocity) curve, but by setting an
acceleration/deceleration time, the constant velocity is set freely.
With the MC (general name: MCV50) curve, the constant velocity
section is 50%
Note: Accelleration/decelleration time is set to one-half or less
of movement time. If accelleration/decelleration time
setting exceeds one-half of movement time, the cam curve
is automatically changed to an MS (modified sine wave)
curve.
In the example, accelleration/decelleration time (ta) is set to 0.5
sec. for movement time (t
1
): 4 sec., a speed pattern that sets the
constant velocity to 75% is created.

Selection guide
With the MC2 curve, the model is selected using the
following formula:

1. Continuous
rotation
: Continuously rotates at a set speed until
the continuous rotation stop signal is input.
2. Equal index
position stop
: If used with equal division designation,
stops at an equal division when the
continuous rotation stop signal is input.
3. Timing output : If used with equal division designation, the
timing output pulse is output at the equal
division during rotation.
In the example, the shaft accelerates at acceleration
time: ta to set speed: N, and when a continuous rotation
stop is input, stops with deceleration time: td.
Selection guide
For continuous rotation, select the model with the following formula.

The above formula applies for ta≤td. If ta>TD, then
replace ta with td, and select.
Note 1) The maximum rotation speed will be limited
during continuous rotation. Use accordingly to actuator
specifications.
