The CIB is a stand-alone closed-loop controller board for Firgelli actuators. Supported input signals include 4-20mA, 0-5V, RC/Hobby Servo Compatible, and 1kHz PWM. Each CIB will control one actuator using a software-based algorithm running on a PIC 16F688 micro controller. The micro controller is socketed and also in-circuit user-programmable.¹

The CIB is initially configured as an "evaluation board" that includes a battery holder (3 AAA cells not included) and a hand-operated linear slider (labeled P1 on reverse) that can be used to control the actuator for demonstration purposes. By changing an on-board jumper J1, and replacing the battery power supply with an external 5-12 volt source, the CIB can then be used to control a variety of actuators using any of the supported control modes. The minimum step size allowed in the control software can be adjusted for each type of actuator or application. This is done on the board using a small trim pot P2.

Operation

When the CIB is powered up, it will repeatedly scan pins 2, 3, 4 on the control interface connector X6 (see reverse for External Connections Detail illustration) for an input signal that is valid under any of the four supported interface modes. When a valid signal is first detected, the actuator will self-configure to the corresponding interface mode, and all other interface modes and input leads are disabled until the actuator is next powered on. Jumper J1 must be set for external control before using external inputs to the control interface. If J1 is set to POT, then the slider P1 can be used to control the actuator.

The sensitivity or accuracy of the actuator control algorithm can be set by adjusting the trim potentiometer P2. Turning P2 clockwise will allow the actuator to move in smaller increments and be more accurate. However due to the differences in actuator types this may cause jittery or unstable behaviour. If this occurs P2 should be turned counter-clockwise to decrease the sensitivity. Each time P2 is adjusted, the power to the CIB must reset before the new setting will take effect.
