EXERCISE 239: Connect servo motor with computer
through servo drive

Objectives

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

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.
1 Sinamics V90 Servo drive. 2 Fuse (Type E) switch (optional).
3 Line filter (optional). 4 DC power supply 24V (optional)
5 External braking resistor (optional). 6 Simotics S-1FL6 servo motor.

7 RS485 interface cable. 8 USB / Mini USB cable.
9 SD / Micro SD card 10 Host controller (SIMATIC S7-1200).
11 Set point (Modbus) cable, 50 pins, 1 m. 12 Set point cable, 50 pins, 0.5 m (PN).
13 Encoder cable. 14 Shielding plate (in V90 package).
15 Hose clamp (attached on power cable). 16 Power cable.
17 Brake cable.

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.
