Chapter 2: Safety

 

Rev A, June 20, 2022 

Page 3

 

 

When  unpacking  the  servo  drive  electronics,  caution  should  be  used  to  protect  against  static  electricity 
damage. Failure to use proper static protection may cause damage to the servo driver boards and void the 
manufacturer’s warranty. 

 

Galvanometers packaged with servo drivers (and mirrors) are factory tuned as a set. Each galvanometer 
is tuned to a specific a servo driver and MUST stay together as a set. For systems using more than one 
galvanometer and servo amplifier, the units are not interchangeable. Servo driver boards have a copy of 
their mating scanner serial number on the bottom.  

 

Servo drivers must be properly attached to a heat sink. Refer to Chapter 7: Heat Sink Requirements for 
proper  heat  sinking  instructions.  Failure  to  heat  sink  the  servo  driver  could  result  in  overheating  of 
components, which could damage the driver and void 

the manufacturer’s warranty. 

 

Every servo driver is tuned to accept a specific input voltage range. Using input command voltages outside 
of  this  range  may  cause  hardware  damage.  Thorlabs  will  not  be  responsible  for  damage  as  a  result  of 
command input voltages that exceed the specified voltage range. 

 

Proper voltage and ground need to be supplied prior to operation. The power supply should have sufficient 
voltage  and  current  for  the  application.  Noisy  power  supplies  can  result  in  poor  scanner  performance. 
Switching power supplies can often introduce unwanted noise. 

 

Be sure that the mirror does not collide with any other mirrors or objects. 

 

Your optical scanners were carefully tested and inspected before packaging. Please report any damage to 
your shipping company immediately.
