1 Introduction
1.1 Before you start
Before operating this product, read the safety instructions in the related Operating
Instructions.
This product is for industrial use only.
Electrical connections must be made by qualified electrical personnel.
1.2 About this document
This Quick Start Guide is intended to help you set up a MINAS servo drive system. It is
based on information from the MINAS series manuals and the practical experience of our
engineers.
Step-by-step instructions will guide you through a real-time auto-gain tuning procedure
for a MINAS servo driver. The autotuning is performed with the PANATERM configuration
software.

2 Functional overview
2 Functional overview
Auto-tuning is required for all applications to adjust the servo motor to the specific
mechanical conditions. You can choose one of the following auto-tuning functions:
• Fit-gain tuning
• Real-time auto-gain tuning
This Quick Start Guide explains how to perform real-time auto-gain tuning.
While the fit-gain tuning function guides you through an automatic fine-tuning process, real-
time auto-gain tuning mainly adjusts the rigidity of the machine. If you are using a MINAS
A6 servo driver, first try fit-gain tuning. If fit-gain tuning was not successful, perform real-time
auto-gain tuning. Both methods can be executed using PANATERM.
If possible, you should perform real-time auto gain-tuning on the machine with the servo
motor and the mechanical loads connected and with the actual movements.
Usually, auto-tuning has the following goals:
1. Reduce the settling time to reduce cycle times.
2. Reduce mechanical vibration to increase the life time of the machine.
3. Reduce overshoot and undershoot to reach the target position within the allowed
hysteresis.
4. Decrease the response time to reach the target position faster.

Example
A MINAS A6SF servo driver is connected to a servo motor, which is coupled to a belt. The
control mode is position control. A continuous movement within the mechanical limits, no
mechanical vibration, no overshoot or undershoot, and a reduced settling time are required.

3.1 Recommendations for wiring
It is the customer's responsibility to apply the countermeasures that they consider necessary
to comply with current regulations on wiring, safety and reducing EMI.
Do not forget to meet the specifications indicated in the hardware manual for each of the
devices being wired. If any specifications in the manual conflict with the information in this
document, the manufacturer's manual takes preference.
For detailed information on reducing EMI, please refer to Recommendations for EMC-
compliant wiring of servo drivers and motors.
3.2 Connectors of the servo driver
XA connector (main power connector)
Connect the power supply cable to the XA connector. For a 1-phase power supply of 230V,
connect a 2-wire cable to the servo driver as illustrated. The L2 pin is not used in 1-phase
mode.

XB connector (motor connector)
Connect the motor cable to the XB connector. The wires are labeled with the letters U, V, and
W. Do not change the sequence of the motor phases, e.g. by connecting V to W.

Use the PC configuration software PANATERM to perform auto-tuning.
1. Connect your PC to the X1 connector and turn on the servo driver.
2. Start the PANATERM configuration software.
The software automatically detects the type of servo driver connected.
3. Select “OK” and confirm the connected series by selecting your type of servo driver.
4. Start a trial run, following the instructions in Quick Start Guide QS5000, PANATERM -
Trial run.
5. While the motor is performing a repetitive, constant movement, select the “Tuning”
tab.
