Lecture 1

- Setting up a Servo system

In this training lecture, you will get acquainted with servo motors and servo drives. What are the parts of a servo drive and servo motor and what models of PLCs do we need to control the servo drive through pulse?

Lecture 2

- Set up a Servo with pulse output

- Show PLC wiring

- Differences in types of pulse outputs

- How to connect PLC and Servo

- How to choose a servo

- Introducing servo Inputs and outputs

In this lecture, you will get acquainted with some of the servo settings and we will explain servo drive cabling. You will also learn about different types of pulse outputs and then work with the inputs and outputs of a servo drive. Finally, we will teach you how to choose a serving system for your specific application.

Lecture 3

- Servo wiring

In this chapter, you will learn wiring between PLC and Servo

Lecture 4

- Introducing the ACC instruction

In this chapter, you will get acquainted with the ACC instruction.

In this chapter, you will get acquainted with the ACC instruction.

ACC(888) outputs pulses to the specified output port at the specified frequency using the specified acceleration and deceleration rate.

ACC(888) starts pulse output on the port specified in P using the mode specified in M using the target frequency and acceleration/deceleration rate specified in S. The frequency is increased every pulse control period (4 ms) at the acceleration rate specified in S until the target frequency specified in S+1 and S+2 is reached.

The pulse output is started each time ACC(888) is executed. It is thus normally sufficient to use the differentiated version (@ACC(888)) of the instruction or an execution condition that is turned ON only for one scan.

Lecture 5

- Introducing the INI instruction

In this chapter, you will get acquainted with the INI instruction.

INI(880) is used to start and stop comparison for a comparison table, to change the present value (PV) of a high-speed counter, to change the PV of an input interrupt in counter mode, to change the maximum value of the ring counter (CJ2M only), to change the PV of a pulse output (e.g., to 0 to establish the origin), to stop pulse output, or to change the settings for origin searches/returns (CJ2M only).

Lecture 6

- Introduction of pulse output flags

- Start/Stop servo with slope by the ACC instruction

When working with PLC pulse outputs, there are a number of flags that can be used in programming. In this training lecture, you will get acquainted with these flags and learn how to use them. Also in this lecture, a simple start and step servo program have been written with acceleration and deceleration using the ACC instruction.

Lecture 7

- Introducing the PRV instruction

PRV (881) reads the High-speed counter PV and pulse output PV and interrupt input PV in counter mode.

PRV (881) reads the data specified in C for the port specified in P. The possible combinations of data and ports are shown in the following table.

(0000 to 0003 hex): Pulse output

(0010 to 0013 hex): High-speed counter input

(0100 to 0107 hex): Interrupt input in counter mode

(1000 to 1003 hex): PWM (891) output

Lecture 8

- Introducing the SPED and PULS instruction

- Introducing Absolute and Relative Movements

- Solve a simple example of a reciprocating motion

SPED (885) is used to set the output pulse frequency for a specific port and start pulse output without acceleration or deceleration.

SPED (885) starts pulse output on the port specified in P using the method specified in M at the frequency specified in F. Pulse output will be started each time SPED (885) is executed. It is thus normally sufficient to use the differentiated version (@SPED (885)) of the instruction or an execution condition that is turned ON only for one scan.

PULS (886) is used to set the pulse output amount (number of out­put pulses).

PULS (886) sets the pulse type and a number of pulses specified in T and N for the port specified in P. Actual output of the pulses is started later in the program using SPED (885) or ACC (888) in independent mode.

Lecture 9

- Introducing the PLS2 instruction

- How to draw a pulse output diagram in CX-Programmer

PLS2(887) outputs a specified number of pulses to the specified port. Pulse output starts at a spec­ified startup frequency, accelerates to the target frequency at a specified acceleration rate, decel­erates at the specified deceleration rate, and stops at approximately the same frequency as the star­tup frequency.

ITPL (893) outputs a 2 to 4 axes linear interpolation to the specified port.

ITPL (893) starts pulse output from the port specified in C1 (port0~3) using the method specified in C2 (axis2~4) at the start frequency (1 in the diagram) and acceleration/deceleration rate (2 in the diagram) in S.

ITPL (893) supports at most 2 linear interpolation operations. The pulse output port method is determined by the settings of linear interpolative port specified in C1.

The interpolated axes are determined by the settings specified in C2.
