EXERCISE 240: Connect servo motor with computer
through servo drive and perform parameter

programming

Objectives

At the end of this exercise you shall be able to:
• to connect servo motor with servo drive using siemens SINAMICS V90 software and perform parameter
programming.

Requirements

Tools/Equipments/Instruments

• Combination plier 200mm - 1 No. • Servo Drive- SINAMICS V90)
• Screw Driver set with neon tester Compatible to 10 HP motor - 1 No.
10mm- max - 1 Set. • Connecting wires as required - as reqd.
• Spanner set 6mm to 32mm - 1 Set. • V-Assistant software /
Materials/Components commissioning tool - 1 No.
• TIA portal software through
• Servo Motor 1phase/ 3phase, Sinamics S7 controller - 1 No.
415V, 20A, 50Hz - 1 No.

Procedure

Servo Drive with Servo Motor:
The SINAMICS V90 servo drive is integrated with digital input/output interface, pulse train interface and analog
interface. It can be connected either to a Siemens controller like S7- 200, S7-1200 or S7-200 SMART, or to a
third-party controller. Absolute position information can be read from the servo drive by the PLC via RS485 port.
A configuration software tool, SINAMICS V-ASSISTANT, can be installed on a PC. The PC can communicate
with SINAMICS V90 servo drive with a USB cable for performing parameter settings, trial run, status display
monitoring, gain adjustments, and so on.
Parts of servo drive- refer exercise 238 .
Commissioning –refer 239
Illustration shows an example of the SINAMICS V90 servo Commissioning purpose when the servo drive
is powered on for the first time, you can perform a test run with the BOP or the engineering tool SINAMICS
V-ASSISTANT to check:
• Whether the mains supply has been connected correctly.

• Whether the 24 V power supply has been connected correctly.
• Whether the cables (power cable, encoder cable, and brake cable) between the servo drive and the servo
motor have been connected correctly.

• Whether the motor speed and direction of rotation are correct.
Prerequisite:
• The servo drive is connected to the servo motor without load.
• No PLC is connected to the drive system.
The SINAMICS V90 servo drive is designed with a Basic Operator Panel (BOP) on the front panel of the servo
drive
