An automatic tool changer is used in CNC machine tools to improve the production and tool carrying capacity of the machine. It changes the tool very quickly, reducing the non-productive time. It is also used to change worn out or broken tools. 

 

 

Technical Requirements

The load is the motor connected to the reducer, which drives the rotary table to rotate and quickly reaches the designated station. The motor is required to accelerate and decelerate rapidly, and the maximum speed is 6000 rpm.

The servo is required to start smoothly with minimum jitter.

The servo is require to remember power-off position.

 

Solution

 

The ISA-7 servo MSC control mode is adopted. Its servo absolute encoder ensures that the power-off position is saved. The servo monitoring parameters allow to monitor the servo running state, running current, load rate and other important parameters. The motor rated power is 0.4 kW, rated torque is 1.27 Nm and the rated speed is 6000 rpm.

 

 

 

 

Technical Advantages and Customer Benefits

High-precision positioning control with 17-bit high-resolution absolute encoder, satisfying the needs of high-precision positioning control and smooth low-speed operation.

Built in two sets of automatic notch filters and one set of manual filter, effectively suppress the mechanical resonance and make the operation smooth.

Through the network interface of the RS485 of the ISA-7, the user is able to use ISA Pro software to modify parameters and record wave forms for fast troubleshooting.

The absolute encoder remembers the servo position when the power is down and resume operation quickly.
