Chapter 6 - Parameter Description [FUN]
6-10
Accel/Decel Pattern: ‘U-curve’
FUN-04: Start Curve for S-Curve Accel/Decel Pattern
FUN-05: End Curve for S-Curve Accel/Decel Pattern
These parameters change the curvature of the
acceleration and deceleration ramps. They also affect
the actual acceleration and deceleration times by the
following formulas:
Actual accel time = Preset accel time+ Preset accel
time *Starting curve ratio/2 + Preset accel time *
Ending curve ratio /2
Actual decel time = Preset decel time + Preset decel
time * Starting Curve ratio/2 + Preset decel time *
Ending curve ratio/2
FUN-10~12: Pre-heat
This function allows the drive to apply low levels of
DC current to the motor to prevent moisture from
entering and condensation from occurring inside the
motor when stopped. When active, the display shows
DCB in the status field.
The Pre-heat function is activated when FUN-10 [Pre-
heat] is set to “Yes” and one of the multi-function input
terminals (I/O-20~27) is set to the “Pre-heat” function.
The Preheat function is only active when the drive is
stopped and the defined terminal is activated.
