MINAS A5 servo driver

Ordering code for Drivers

Regenerative Energy Discharge

• A regenerative resistor is used to discharge regenerative energy, which is the energy generated when stopping a load with a large moment of inertia or when using this unit in vertical operation. This energy is returned to the driver from the motor.
• Frame A and Frame B model drivers do not contain a regenerative resistor. We recommend that you connect an optional regenerative resistor.
• Frame C to Frame F model drivers contain one regenerative resistor; however , adding an optional regenerative resistor provides additional regeneration capability.

Dynamic Braking 

• With parameter settings, you can select dynamic braking, which shorts servomotor windings U, V and W at Servo-OFF, during positive direction/ negative direction over-travel inhibition, and during power shutdown and tripping of the circuit breaker.
• The desired action sequence can be set up to accommodate your machine requirements.

Parameter Initialization 
Using the front panel or by connecting a PC, you can restore the parameters to the factory settings.

Disturbance Observer 
By using a disturbance observer to add an estimated disturbance torque value to the torque canceling command, this function diminishes the impact of the disturbance torque, reduces vibration, and offsets any speed decline.

Torque Feed Forward 
The Torque Feed Forward function performs a comparison with feedback and calculates the amount of torque to add to the necessary torque command in the command for actuation.

Friction Torque Compensation
This function reduces the effect of machine-related friction and improves responsiveness. Two kinds of friction compensation can be set up: unbalanced load compensation, which compensates with a constant operational offset torque; and kinetic friction, which changes direction in response to the direction of movement.

3-Step Gain
A 3-step gain switch is available in addition to the normal gain switch.This chooses appropriate gain tunings at both stopping and running.The 3-step gain switch gives you choices of 3 diffent tunings for normal running, stopping for faster positioning and at stopping.The right gaing tunings achieve lower vibration and quicker positioning time of your application.

Inertia Ratio Conversion
You can adjust right inertia ratio by Inertia Ratio Conversion input(J-SEL).When you have significant load inertia changes, it can adjust unbalanced speed and position gain turning conbination.It ends up quicker response of your system.

Input/Output Signal Assignment
You can use the parameters to arbitrarily allocate the universal 10 inputs and 6 outputs. (Inputs can be selected as either A contacts or B contacts). The Panaterm setup software provides an exclusive screen for a more simplified setup.

Torque Limiter Switching
You can use the I/Os to set up torque limits. These can be used for applications such as simplified pressure, tension control, and sensor-less homing.
