Delta CTA series and assist the users to operate CTA as well as getting familiar with its functions. The date of the latest update is shown in the bottom left of the page. - Page 3 Make sure that you place the sensor, other input devices, signal cables and CTA away from the interference source. It will require 200ms after CTA is switched on for the activation of the internal power and default value reset. CTA may not operate normally during this period of time.

1.6 Terminal Definition CTA combines the functions of timer, counter and tachometer; therefore, the definitions of input terminals in different modes are slightly different. CTA has 4 terminals ready for inputs. Take the pins in counter mode for example, (see figure 1). - Page 6 CTA for the connection.

After the setup is completed, press page you are in and return to the main menu. Select functions: There are 4 modes in CTA, (left to right) timer, counter, tachometer and timer + counter. Select timer mode: counting up and counting down Select output modes: There are 12 output modes in the timer. - Page 10 If the clear signal is enabled (Hi) when the start signal is at rising edge, the output will stop immediately. - 10 - © DELTA ELECTRONICS, INC.

Select input modes: counting up, counting down, command counting up/down, individual counting up/down, quadrature input Select output modes: CTA offer 11 output modes, among which mode S, T and D are only valid with input modes Ud_A, Ud_b and Ud_C. See 2.2.2 for more details. - Page 15 2.2.2 Setting up input mode of the counter CTA offers 5 counting modes: counting up, counting down, command counting up/down, individual counting up/down and quadrature input.

2Hi1Lo, and assume the first set value is 100 (2Hi) and the second 50 (1Lo), the output value of the tachometer will be below 100 (2Hi) and above 50 (1Lo) and CTA will not perform an output. If the set value exceeds the range, CTA will perform an output. - Page 20 ※ = Number of pulses per revolution (ppr) Example 1: Connecting Delta servo drive with a servo motor and measure the current rotation speed by CTA The built in encoder in Delta servo motor is 10,000ppr with four phases, OA, OB, 2,500ppr.

Page 22: Timer + Counter (Mixed Mode)
In this mode, the timer and counter both have a phase signal input; therefore, part of the functions will be limited. For example, there are 12 output modes for the timer of CTA, but only 8 output modes available in the timer + counter mode (Rcy2, Scon, Ston and Stoff are not available). -
Page 23: On Cut-To-Length Machine
3.1 On Cut-To-Length Machines The machine adopts the counter function in CTA and acquires the feedback signal from the encoder for measuring the actual operation distance. When the set distance is reached, the output signal will enable the knife for the cutting. - Page 24 CP1 (phase A) and Assume The set value in the CTA counter is 160mm. When the counting reaches 160mm, an output signal will be given to the knife for the cutting. See figure 2. In the figure, we can see the diameter of the roller is 44.8mm...
