Delta A2 servo has many pulse sources, such as main encoder, auxiliary encoder, pulse command, which can be used for positioning command (PT mode), high-speed capture/comparison, E-CAM master pulse and so on. In addition, the various pulse sources can be also output from CN1 for the host controller to count. Due to the large number of parameters, it is often confusing. This article draws the relevant functions and parameters into a block diagram to facilitate quick and comprehensive understanding for readers’ reference.

In automation applications, servos are used as motion control actuators. In addition to performance requirements, safety protection is also very important. This article summarizes all the emergency stop and safety protection functions of Delta Servo, and explains the use timing, trigger conditions, and corresponding deceleration time.

ASDA-Soft Building CAM Table – (2) Trapezoidal Curve

Archer Delta A2 Functions 2019-07-042019-07-04Delta A2, Fly Saw 0 Comment

Trapezoidal CAM curve is being widely used in the flying-shear and labeling application. This article explains how to build a “trapezoidal cam table” with software ASDA-Soft, which is the foundation of the flying-shear application including adjusting the profile of the curve, synchronizing the speed of master and slave axes, configuring the output angle of the synchronization area , etc. Applicable to both ASD-A2 and ASD-M-R series servos!

A2 E-CAM Example: Flying Shear (2) – Parameter setting

Archer A2 applications 2019-02-142019-07-04Delta Servo, Fly Saw 0 Comment

Following the sample program in A2 E-CAM Example – Flying Shear (1) – Basic Operation, this article includes the further introduction of the parameter configuration. Due to the difference in specifications of each flying shear mechanism, it is not appropriate to apply the sample parameters completely unchanged. This article will elaborate the related parameters and the principle for the proper configuration.

Delta A2 Servo Quick Start and FAQ

Archer Delta A2 Functions 2019-01-102021-03-04Alarm handling, Delta A2, Delta Servo 0 Comment

This article contains frequently asked questions and alarms for the Delta ASD-A2 servo system for readers’ reference：

Q1，AL.13/AL.14/AL.15 is displayed on power-up, how to deal with it？

A => For safety reasons, the default functions of the servo DI 6/7/8 are reverse limit/forward limit/emergency stop, and are all B (normally closed) contacts, so when there is no limit switch connected, The above alarm will occur when power is applied. If the motor (not the linear motor) is not connected to the mechanism, the user only wants to test it. You can temporarily remove these protection functions by setting the hundred digits of P2-15, P2-16, and P2-17 from 0 to 1. , change to A (normally open) contact; or directly set all three parameters to 0, which means to turn off these protection functions ! Users should take extra care when testing and fix the motor firmly for safety !

A2 E-CAM Example: Flying Shear (1) – Basic Operation

Archer A2 applications 2019-01-082019-02-14Delta Servo, Fly Saw 0 Comment

Flying shear is a common application of the E-CAM function. This article provides the Delta A2 servo’s sample program of the flying shear, including the trapezoidal E-CAM curve, parameter file with the PR commands, so users can follow the instruction and easily run the program to help with understanding the operating principle of flying shear and how to utilize it. Generally, the master axis of the flying shear is the encoder signal of the feeding axis while the slave axis is the sliding table, which is the target to be controlled in this example. Please refer to the video clip in the following links for the flying shear application => YouTube
