BRAKE DEADBAND  

 

Offset Between the actual set point and the beginning of clutch action for the PID loops.  

Used  to  prevent  oscillation  between  clutch  and  brake  when  running  at  steady  speed  

(Default = 50 RPM)

BRK OFF DLY    

 

This  is  a  programmable  delay  from  issuance  of  the  stop  command  to  release  of  the 

clutch contactor by the control.  Note that this timer is overridden by the contactor on 

input from the press control.    

Default = 0.50 Seconds

The EC-2000-CES Control operates in strokes per minute.  It uses RPM X gear ratio to establish a 

operating speed in strokes per minute.  All of the speeds set in process are multiplied by the 

gear ratio to establish an operating speed.  Note the control can also display an output speed is 

strokes per minute from the resolver.  This can be used to correct the gear ratio if the proper 

value is not known to obtain the proper output speed.  Max RPM / Gear Ratio = Max SPM

ANGLE #1           

 

The  control  has  six  programmable  angle  and  speeds.    For  example,  when  the  control 

sees Angle #1 as the last position it has passed, it will run at Speed #1  

Range: 0 to 360 Degree (Note 360 DEG is ignored)
