When to use the MASSO Differential Receiver Module

The MASSO Differential Receiver Module is designed to provide support for Stepper or Servo motor drives that do not support advanced differential signals.
Differential signals provide great immunity to electromagnetic noise that can interfere with motor control signals and cause issues with motor positioning or might cause unexpected motion on the machine axis.
VFD drives for spindle motors and plasma cutting sources generate high electromagnetic noise and can interfere with motor position signals.
With differential signals, long cables with STEP and DIRECTION signals from the MASSO controller can be run to the motor drives.
Do not mount the Differential receiver next to the controller. Mount it next to the drives.
Up to 50m between MASSO and the MASSO differential receiver module can be achieved when using a high quality twisted pair cable with uniform impedance and low attenuation.
The distance between the MASSO differential receiver and your Drive should be kept as shot as possible.

INFORMATION: The MASSO Differential Receiver Module can be used to control up to 5 axis motor drives and can also provide 5 volts so that no external 5 volt power supply is required.

Some of the example drives that do not support differential signals

Wiring example with a common negative signal

The below diagram shows a GECKO G203V drive that takes TTL signals with a common negative.

Mount the Differential receiver close to the drives.

Wiring example with a common positive signal

The below diagram shows a GECKO G340 drive that takes TTL signals with a common positive. The MASSO Differential Receiver Module provides 5 volts and no external 5 volt power supply is required.

Mount the Differential receiver close to the drives.
