How to Program
Function:
Select passive load [0] for conveyers, fan and pump
applications. Select active load [1] for hoisting
applications. When active load [1] is selected, set
min. current at low speed (par. 1-66) to a level
which corresponds to maximum torque.
1-68 Minimum Inertia
Range:
0-VariableLimit
*
Depending on motor data
Function:
Set the minimum moment of inertia of the
mechanical system.
Par. 1-68 and par. 1-69 are used for
pre-adjustment of the Proportional Gain in
the speed control (par. 7-02).
1-69 Maximum Inertia
Range:
0-VariableLimit
*
Depending on motor data
Function:
Set the maximum moment of inertia of
the mechanical system.
" 1-7* Start Adjustments
1-71 Start Delay
Range:
0.0 - 10.0 s
*
0.0s
Function:
Enables a delay of the starting time. The adjustable
frequency d rive begins with the start function
selected in par. 1-72 . Set the start delay time
until acceleration is to be gin.
1-72 Start Func tion
Option:
DC hold/de lay time [0]
DC Brake/delay time [1]

Coast/delay time [2]
Start spee d/ current cloc kwise operation [3]
Horizontal operation [4]
VVC
plus
/Flux clockwise [5]
Function:
Selects the start function during start
delay (par. 1-71).
Select DC hold/delay time [0] to energize
the motor with a DC holding curr ent (par.
2-00) in the start delay time.
Select DC brake/delay time [1] to energize
the motor with a DC braking current (par.
2-01) during start delay time.
Select Coast/delay t ime [2 ] to releas e the
shaft-coasted drive d uring the start delay
time (inverter off).
Select Start speed/current clockwise [3 ] to
connect the function described in par. 1-74 and
par. 1-76 in the start delay time.
Regardless of the value applied by the reference
signal, the output speed applies the setting of the
start speed in par. 1-74 and the output current
corresponds to the setting of the start current
in par. 1-76. This function is typically used in
hoisting applications without counterweight and
especially in applications with a one-armature
motor, where the start is clockwise, followed by
rotation in the reference direction.
Select Horizontal operation [4] to obtain the
function d escrib ed in par. 1-74 and par. 1-76
during th e start delay time. T h e motor rotates in
the reference direction. If the r efere n ce signal
equals zero (0), par. 1-74 Start speed is ignored
and the output speed equals zero (0). The output
current corresponds to the setting of th e start
current in par. 1-76 Start current.
Select VVC
plus
/Flux clockwise [5] for the function
described in par. 1-74 only (Start sp eed in
the start delay time ). The start c u rrent is
automatically calculated.
This function only uses the start speed in the
start delay time. Regardless of the value set b y
the reference sig nal, the output spe ed equals
the setti ng of the star t speed in p ar. 1
-74. Start
speed/current clockwise [3] and VVC
plus
/Flux
clockwise [5] are typically used in hoisting
applications. Start sp eed/curren
t in reference
direction [ 4] is particularly used in a pplications with
counterweight and horizontal movement.
