10. TECHNICAL SPECIFICATIONS
General Information:
Supply Voltage: Line to line 220-1200V (to be specified) + 10%-15%
Frequency: 45 – 65 Hz (fixed or variable frequency source)
Control Supply: 110-230VAC or 110VDC (to be specified) +10% - 15%
Control Inputs: Either same as Control Supply or by special order 24-230V AC/DC (to be
specified)
Load: Three phases, three/six wires, squirrel cage induction motor
Connection type: Standard 3 wire U, V, W connection, or 6 wire Inside Delta (programmable)
Start-Stop Parameters:
RVS-DN FLC: RVS-DN’s Full Load Current (FLC), according to ordering information
Motor FLA: Motor Full Load Ampere (FLA) 50-100% of RVS-DN FLC
Starting Curve 0
(Standard)
2 standard starting and stopping curves
Pump Control Curves (1!,
2!, 3!)
6 field selectable curves preventing over-pressure during start and water
hammer during stop
Torque Control Curve (4) 2 selectable curves preventing over-pressure during start and water hammer
during stop. In addition, these curves may be used for torque control starting of
constant torque applications.
Pulse Start Duration: A pulse of 80% Un, for an adj. time 0.1-1 Sec, for starting high friction loads
Initial Voltage: 10-50% Un (5-80%
(1)
)
Initial Current: 100-400% In (1 current control starting curve, appears when INITIAL VOLTAGE
is displayed, up arrow is pressed, and INITIAL VOLTAGE has reached its max.)
Current Limit: 100-400% of Motor FLA (100-500%
(1)
)
Acceleration Time: 1-30 Sec (1-90 sec
(1)
)
Deceleration Time: 1-30 Sec (1-90 sec
(1)
)
Dual Adjustments: Secondary start stop characteristic for: MOTOR FLA, INITIAL VOLTAGE,
CURRENT LIMIT, ACC. TIME and DEC. TIME
Energy Saving: Energy save for lightly loaded motors
Slow Speed Torque: Torque while motor is at 1/6 nominal speed
Tacho and Linear
Acceleration:
12 field selectable curves – defining gain control, improving tacho feedback
Note:
(1) Refer to section 6.5.5 page 58 for Expanded setting.
Motor Protection:
Too Many Starts: Maximum number of starts, range: Off or 1-10, during a time period 1-60 min.
Starts Inhibit: Time period 1-60 min, when starting is prevented, after too many starts fault
Long Start Time (stall
protection):
Maximum allowable starting time 1-30 sec. (1-250 Sec
(1)
)
Over Current (shear-pin): Three trip functions:
At all time
- If I > 850% of FLC it trips the RVS-DN within 1 cycle (overrides the
value of the O/C – SHEAR PIN setting).
At starting process
- If I > 850% of FLA it trips the RVS-DN after O/C DELAY
(see here after)
At run time
- If I > O/C – SHEAR PIN setting of FLA it trips the RVS-DN after
O/C DELAY
Electronic Overload (I
2
t): Adjustable 75-150% of motor FLA, adjustable trip time at 500% In of 1-10 sec.
Under Current: Trips when current drops below 20-90% In, time delay 1-40 sec.
Optional auto reset after time delay.
Under Voltage: Trips when main voltage drops below 120-600V (600-1100V in RVS-DN 1000V
& 1200V models), time delay 1-10 Sec. Optional Auto Reset.
Over Voltage: Trips when main voltage increase above 150-750V (1100-1440V in RVS-DN
1000V & 1200V models), time delay 1-10 sec.
Phase Loss, Under/over
Frequency:
Trips when one or two phases are missing, or frequency is < 40Hz or > 65Hz.
Optional auto reset.
Phase Sequence: Trips when phase sequence is wrong
Long Slow Speed Time: Trips if operating at slow speed for more than 1-30 sec (1-250 sec
(1)
)
Wrong Connection: Prevents starting, trips if motor is not connected / incorrectly connected to the
RVS-DN (not active in DA:GENERATOR PARAMETERS)
Shorted SCR: Trips if one or more SCRs have been shorted (not active in DA:GENERATOR
