Productivity AMC: Hardware Axis Configuration

To configure your AMC axis, have your unit  added to the hardware configuration in the   Productivity Suite and then select your  AMC unit. There is a quick start video   that will walk through adding the AMC unit to your Productivity PLC and a link to   that can be found in the description below. The AMC configuration is broken into two parts.   Setup for your overall unit and  then the individual axis setups.   To save yourself some time in setting this up, I would advise using the structure feature.   This will create the tags that will be needed  for the complete setup of the axis, and you will   just need to load values into those tags. Here you can define if the PLC Program will   continue to run or go into stop mode if there  is a communication loss to the AMC unit.   This, if enabled, allows an outside device  to enable or disable the entire controller   by requiring this input to be true. Here are some status flags for the AMC unit.   Now let’s look at a single axis configuration.  Each axis is broken into 4 parts.   For status this allows you to map all  the input and output points to a tag,   if you use the structure option this  is all mapped to tags for you.   These will provide the current position and  speed based upon the scaling, which will be   set up in the next tab. And this will give you the  possible error codes for this individual axis.   Here you have 3 options. You can leave the  position in pulse which will not apply any scaling   to the current position or you can define how  many pulses it takes to equal one of these options   and if needed you can define a custom reference.   So, for instance, let’s say it takes 360  pulses to move my application one inch.   This is based upon your actual output not your  encoder. That encoder feedback is defined below.   Here you can define the data type  your position data will be stored in.   If you select an integer, this will be in  whole numbers only. If you select float,   you can have fractional values and  you can define the accuracy here.   This time unit is used to  calculate the axis speed.   You can select this based upon these  options or make a custom reference.   When you enable the encoder for feedback to  your motion - let's say it takes 720 pulses   on my encoder to move my motion 1 inch. So, based  upon my position setup above, I would   have two encoder pulses per 1 output pulse. Here you can use that encoder to allow the AMC   to monitor the deviation of your output to  your encoder feedback. If there is a deviation,   here you can define the max deviation, and how the  unit will react if you reach that max deviation.   This option allows you to use  the axis enable instruction   before you can run motion instructions. This will  also define whether or not the Enable Output 2   is required to be active before a  move command is sent to the axis.   This output is used if your motor  controller requires an external enable.   And if this is enabled then  this will define if the   axis enable output will remain at the last  state during a stop mode on the PLC   This will define if the at rest  output is used for a given axis.   If this is selected as Yes, this will automatically  operate during the start and stop of a move.   This defines whether or not the Drive Ready  Enable is being used for a given axis.   This is useful if you want to bring your drive  ready signal from your motor controller to the AMC   for handshaking ensuring that your downstream  device is ready to receive motion commands. If   the signal goes low at any point during the  operation, then you will have these actions.   These are used to invert the signal of  motor direction and various inputs.   This allows you to define the input and edge   that when true will reset the position  of the axis to this defined position.   Here you can define if the motion is rotary  or linear. If this is selected, it defines the   motion as rotary. So, if the pulses get to this  value the position will reset to 0 pulses.   And these are your output limits for  velocity, acceleration, and deacceleration.   Once you have all of this set  up just send it to your PLC.   They have really done a great job  making this as simple as possible.   Productivity suppling the tools to get  the most out of your control system.   If you have any questions on the Productivity  line of PLCs, please feel free to comment below   or call into our technical support department.  Click here to see more videos on the Productivity   line of PLCs and click here to subscribe to our  YouTube channel for new products and solutions.
