___________________________________________________________________________________________
8.3 102BExamples of starting curves
8.3.1 146BLight Loads-Pumps, Fans, etc.
INITIAL VOLTAGE – set to 30% (Factory Default)
CURRENT LIMIT – set 300%
ACCELERATION TIME – set 5 sec
Voltage quickly increases to the INITIAL VOLTAGE value and then gradually ramps-up to nominal. Current
simultaneously and smoothly increases to reach CURRENT LIMIT setting or less, before smoothly decreasing
to the operating current. Motor speed will accelerate to full speed quickly and smoothly.
8.3.2
147BHigh Inertia Loads – Fans, Centrifuges, etc
INITIAL VOLTAGE – set 50%
CURRENT LIMIT – set 400%
ACCELERATION TIME – set 20 sec
Voltage and current increase until current reaches CURRENT LIMIT. The voltage is held at this value until
motor is close to nominal speed, then current will begin to decrease. The RVS-DX continues to ramp-up the
voltage until reaching nominal. Motor speed smoothly accelerates to full speed.
Check total starting time and set Max. Start Time to approx. 5
seconds longer than the maximum time required to complete the
starting process
Motor acceleration time
to full speed is as
required?
No
Yes
Apply Start command
If acceleration time is too short, increase ACC.
TIME setting and/or decrease CURRENT LIMIT.
(when decreasing CURRENT LIMIT, make sure
motor increases speed gradually and does not
stall).
