Linear Actuator

A standalone Platform for Animal Manipulation

This is the firmware for the LinearA_2017 (linear servo, i.e. stepper motor with spindle) and project Servo_2015 (standard PWM servo). Setup and control of the Actuator is done via 3 keys, and, for selecting the two end positions, also via two external inputs, please see below. The firmware supports soft-start, i.e. the Actuator speed will be ramped-up during the start phase.

Supported:

Nanotec SMC11-2 Leistungsendstufe
Nanotec Linear Aktuator L2018S0604-T3,5x1

The linear setup procedure consists of 4 steps:

Adjust end position 1. A linear actuator doesn't know about its absolute position, therefore it first moves to to its physical start position (near the motor) after power-up. From that, position 1 can be adjusted.
Adjust end position 2. This is the opposite end position to position 1.
Adjust actuator speed. The actuator permanently moves between the two end points. The speed can be adjusted via S1 and S2.
Asserting S3 the 4th time stores the servo parameters into FLASH and returns to normal operation.
