PID controller. Several of these methods require little knowledge about the actual dynamics of the system to be tuned. If possible, Merrick will tune the PID controller before the feeder is shipped to you. Otherwise, we recommend you use whatever tuning method you are most familiar with. -
Page 34: Gain
Gain This is the amount of gain associated with the PID algorithm. In the MC³, gain is expressed as a percentage. The higher the gain, the more aggressive controller behavior. A purely proportional controller (with no integral and derivative action) would result in constant error. Too much gain can cause the controller to go unstable. -
Page 35: Feedrate Hi/Lo
The feedrate Logical Output alarms are delayed by settable time parameters, “High Delay” and “Low Delay” to prevent frequent cycling. In addition, there is a “Startup Delay” that is active when the feeder is starting up, from either a blocked state or a zero setpoint. The Main Screen displays are not delayed. -

The following are the four types of tachometers that can be used with the MC³: Optical 5 Volt digital encoder, either signal channel or quadrature. Mag/F-25 Merrick F-25 Encoder or a 2 wire current loop magnetic style encoder. MC³ 24.96.EX O&M Manual Page 29 08/14/01 4:34 PM/LDD... -
Page 38: Mode
Stepper Brushless pulse generator. Frequency Frequency generator. Mode Mode determines if direction detection is to be utilized. For direction detection, a quadrature encoder must be connected to the MC³, channel A and/or B. A quadrature encoder allows the MC³ to determine when the belt is moving and will only generate a speed signal if the belt is moving in a forward direction. -
Page 39: Numeric Parameters
SIMULATOR The belt speed is calculated from the output to the belt drive (SCR OUTPUT), and the relation detected between the output and the actual speed with fully operational tachos, initially set to 100 %. Numeric Parameters Nominal Ratio - This value is the ratio between the two tachos. The ratio of Tacho 2 to Tacho 1 is used for comparison. -
Page 40: Display Dampening
Display Dampening These factors are used to dampen the displayed values for the feedrate and speed. Increasing the value will cause more dampening of the displayed feedrate or speed. Note that the Speed Factor is critical for the dynamics of the controller, and the Feedrate Factor is not. Set the Speed Factor for a low belt speed. -
