Parameter Description
Settings
(Default Value)
If the ‘Valve Inertia Time’ is set to 5 seconds, ‘Valve Backlash Time’
is set to 3 seconds and ‘Minimum ON Time’ is set to 4 seconds; as
per the above example; the Final Pulse Time will be calculated as:
Final Pulse Time = (30 - 5) + 3 + 4 = 32 seconds
The ‘Motor Run Time’ is expressed in seconds and settable in 1
second resolution. The motor run time should be very accurately
measured and entered as a value for this parameter. The
minimum value set for this parameter is restricted to the value set
for the parameter ‘Minimum On Time’ for the motor.
VALVE INERTIA TIME
This parameter defines the time taken by the valve (and motor) to
stop moving after the drive pulse is removed. This is due to the
mechanical inertia of the valve (and motor) and is independent of
the direction (Forward or Reverse) of the motion.
0.0 to 20.0
(Default :0.0)
VALVE BACKLASH TIME
This parameter defines the time taken by the gear-teeth to get
locked while changing the direction (from Forward to Reverse or
vice-a-versa).
0.0 to 20.0
(Default :0.0)
User Manual

MINIMUM ON TIME
This parameter, defines the minimum pulse duration (Forward or
Reverse) that the controller will execute. That is, the controller
holds and accumulates the Valve Position shifts demanded by the
control algorithm until it equals or exceeds the ‘Minimum On Time’
set by the user.
0.3 to Motor Run Time
(Default :1.0)
