Inverse Master Mode Example
The Inverse Master Mode Example demonstrates how scaling and setpoint Control
Parameters are entered for a typical Inverse Master mode of operation:
It takes 10 seconds to move a product through a heat treat oven when
the conveyor motor is running at 1500 RPM. The conveyor motor shaft
is equipped with a 60 tooth ring kit. Set Master Setpoint 1 (CP-01) so
that the product is in the oven for 20 seconds. Set Master Setpoint 2
(CP-02) so that the product is in the oven for 15 seconds.
Table 3-15 shows the scaling Control Parameters that would be entered in the ML–Trim
for this example.
Table 3-15 Inverse Master Mode Control Parameters Example
CP Parameter Name Parameter Value
CP-62 Inverse Scaling 2
CP-31 PPR Feedback 60
CP-34 Max RPM Feedback 1500
CP-20 Master E.U. 10.0
CP-01 Master Setpoint 1 20.0
CP-02 Master Setpoint 2 15.0
After the Scaling and the Master Setpoints for your system have been entered, you can
enter the Acceleration/Deceleration Control Parameters for the Inverse Master mode.
The Acceleration/Deceleration Control Parameters are identical for both the Inverse
Master and the Inverse Follower modes of operations. Acceleration/Deceleration is
discussed in
Operation: Control Parameters, Acceleration/Deceleration, page 3-26.
The following section demonstrates how to enter Control Parameters for the Inverse
Follower mode of operation.
