6.5.5 Switch # 7 – Expanded Settings
EX
PANDED SETTINGS corresponds to:
Parameter Dip switch #7 - Off Dip switch #7 - On
INITIAL VOLTAGE 10-50% 5
(1)
-80%
CURRENT LIMIT 100-400% 100-500%
ACCELERATION TIME 1-30 seconds 1-90 seconds
DECELERATION TIME 1-30 seconds 1-90 seconds
MAX. START TIME 1-30 seconds 1-250 seconds
PHASE LOSS Y/N Yes

Yes/No

MAX SLOW SP TIME 1-30 seconds 1-250 seconds
O/C or WRONG CON protection
in Inside Delta mode.
Protection active in normal
set
(3)
Protection active in high set
(3)
OVERLOAD TRIP protection. OVERLOAD TRIP will be
active after Run LED is Lit.
(Motor is at full voltage)
(4)
OVERLOAD TRIP will be active
after MAX. START TIME has
elapsed.

Notes:
(1) Setting the INITIAL VOLTAGE to lower than 10% is not practical for loaded motors.
(2) Refer to section
9 page 95. See PHASE LOSS protection and refer to the warning below.
(3) Refer to section
9 page 95. See O/C or WRONG CON protection.
(4) In order to avoid OVERLOAD TRIP in special cases (very high inertia loads), where at the end of the
acceleration process, although motor is at full voltage (Run LED is Lit) and the current does not reduce to
nominal, set Dip switch #7 to On causing the OVERLOAD TRIP to be active only after MAX. START TIME has
elapsed.
WARNING!
Operator’s
responsibility!
(1) EXPANDED SETTINGS are for use in very special applications only!
Do not set to switch #7 to on unless RVS-DN is significantly larger than the
motor! When using expanded settings for the RVS-DN you must be extremely
careful to avoid damaging the motor or RVS-DN.
(2) Only cancel PHASE LOSS protection when the operator is sure that no real
phase loss exists and PHASE LOSS protection is activated.
This situation can occur in rare cases when there is no real fault but the RVS-
DN recognizes unusual behaviour like when THDV (Total Harmonic Distortion in
Voltage) in the network is high.
If this is a true case of PHASE LOSS then after cancelling PHASE LOSS
protection the motor will single phase and most likely be tripped by the over load
protection mechanism.
6.5.6 Switch # 8 – Software Lock
The software lock preve
nts undesired parameter modifications.
When locked, pressing the Store, ▼or ▲ keys causes the LCD to display UNAUTHORIZED ACCESS.
6.6 Internal Fan Control
An internal jumper connected between the fan a
nd terminal 2, enables three modes of operation. For fan
power consumption, see technical specification section
10 page 99.
Fan control jumper J1. Refer to section
6.4 page 55 for J1 location.
