DTAV40 Wiring Diagram

The DTAV40 wiring diagram consists of several components, including the control circuit, the power circuit, and the motor. Let’s take a closer look at each one of them.

Control Circuit

The control circuit is responsible for managing the speed and direction of the motor. It receives signals from the motor control interface, such as a potentiometer or a PLC. The control circuit also includes the acceleration and deceleration adjustments, which can be set using the onboard trim pots.

To wire the DTAV40 control circuit, follow these steps:

  1. Connect the control voltage to terminals 1 and 14.
  2. Connect the analog input to terminals 2 and 3 (for voltage input) or 4 and 5 (for current input).
  3. Connect the acceleration adjustment potentiometer to terminals 6 and 7.
  4. Connect the deceleration adjustment potentiometer to terminals 8 and 9.

Power Circuit

The power circuit is responsible for supplying power to the motor. It includes the main contacts, which control the flow of current to the motor, as well as the overload protection, which prevents the motor from overheating.

To wire the DTAV40 power circuit, follow these steps:

  1. Connect the line voltage to terminals L1 and L2.
  2. Connect the motor to terminals T1 and T2.
  3. Connect the overload protection to terminals 11 and 12 (for normally open contacts) or 13 and 14 (for normally closed contacts).

Motor

The motor is the device that the DTAV40 is controlling. It can be either an AC or DC motor, as long as it meets the voltage and current requirements of the controller.

To wire the motor to the DTAV40, follow these steps:

  1. Connect one motor lead to T1 and the other to T2.
  2. Connect the motor ground to the ground terminal provided.

DTAV40 FAQ
