DA180 series servo drive (100W–1kW) 
1. Command smoothing filter 
2. FIR filter 
Torque 
limit 
command 
input 
This  allows  independent  CW  or  CCW  torque 
limit. 
This  can  suppress  1Hz–200Hz  front-end  vibration  and 
entire-machine vibration. 
1:  This  allows  arbitrary frequency  division settings  under 
the encoder resolution. 
2: This supports phase-B reserving. 
1: Internal command speed 1 
2: Internal command speed 2 
3: Internal command speed 3 
4: Zero-point clamping 
You  can  enable  speed  command  inputs  after 
performing  relevant  settings  based  on  the 
analog voltage DC±10V. 
This  allows  independent  CW  or  CCW  torque 
limit. 
The internal eight-step speeds can be switched based on 
external control inputs.

ACC/DEC 
adjustment 
This supports both independent ACC/DEC time setting and 
S-curve ACC/DEC setting. 
In  speed  mode,  this  allows  the  hybrid  speed  or  position 
working manner.
