RA 

– SD Mode 

 

Presetting of the ramp times. Functionality depends on command RMODE. 

RMODE = SD:   In this mode every command value has its own ramp time.  

For example: if you choose set point S:1 also ramp time RA:1 is chosen. 

RMODE = 4Q  

Four quadrants ramp function. See command AA (page 19)
