SCA-SS-30-06   

(30V, 6A) 

 
 
 
The servo amplifier SCA-SS-30-06 is a powerful servo 
amplifier for brushed DC motors with an output range up 
to 150 Watt. 
These operation modes are integrated 

• 

Current control 

• 

I x R control 

• 

DC-Tacho control 

• 

Voltage control 

• 

Optional: encoder feedback 

 
The required operation mode is to be selected with 
jumpers, which are accessible externally at any time. 
This SCA-SS-30-06 servo amplifier is protected against 
over current and overheat. Due to the wide range of 
power supply voltage between 11 to 30 V DC the SCA-
SS-30-06 can be used very flexible with different kinds 
of power supplies. The robust aluminium case has been 
constructed for different methods of mounting it, 
therefore a fast and easy integration is provided. Screw 
terminals and a durable controller-design allow a fast and straightforward commissioning.

1.  Safety notes 

1.1.  Skilled personnel 

The installation and commissioning have to be done only by skilled personnel. 

 

1.2.  Laws 

The user has to ensure the correct installation of the servo amplifier and additional equipment 
according to valid laws and rules. 

 

1.3.  Remove load 

For first commissioning the motor should run with free shaft which means without load. 

 

1.4.  Additional safety components 

Electronic components are not free of failure or damage. Therefore plants have to be installed with 
additional device and installation protecting components. A safe and stable state has to be ensured in 
the case of damage of some devices, wrong handling, cable disruption and other cases of any kind of 
malfunction.
