4-Q-DC Servoamplifier ADS 50/5
Order number 145391
Operating Instructions
July 2009 Edition
The ADS 50/5 is a powerful servoamplifier for
driving permanent magnet DC motors up to
250 Watts.
Four modes can be selected by DIP switches
on the board:
•
Speed control using tacho signals
•
Speed control using encoder signals
•
IxR compensated speed control
•
Torque or current control
The ADS 50/5 is protected against excess
current,
excess temperature and short circuit on the
motor winding. With the FET power transis-
tors incorporated in the servoamplifier, an
efficiency of up to 95 % is achieved. A built in
motor choke combined with the high PWM
frequency of 50 kHz allows the connection of
motors with a very low inductivity. In most
cases an external choke can be omitted.
Thanks to the wide input power supply range of 12 - 50 VDC, the ADS 50/5 is very versatile and can be used
with various power supplies. The aluminium housing makes installation simple, with terminal markings for easy
connection.
