34
The source of the direction command is defined with this parameter. With
CP.34 one does not modify the direction command of the fixed frequencies
(CP.19... 21). This parameter is an "Enter" parameter.
Value
Function
0
Digital selection (op.2); negative set values are set to zero
1
Digital selection (op.2); the sign of the value has no effect on
the direction of rotation
2
Setting by way of terminal strip forward/ reverse; negative
set values are set to zero (factory setting)
3
Setting by way of terminal strip forward/ reverse; the sign of
the set value has no effect on the direction of rotation; the
speed is the absolute value of the set value
4
Setting by way of terminal strip run, stop (X2A.14) and
forward, reverse (X2A.15); negative values are set to zero
5
Setting by way of terminal strip run, stop (X2A.14) and
forward, reverse; the signs of the set value has no effect on
the direction of rotation; speed is the absolute value
6
Set value dependent, positive value - clockwise rotation;
negative value- counterclockwise rotation; with set value "0"
the unit is switched into status "Low speed" (LS)
7
Set value dependent, positive value - clockwise; negative
values - counterclockwise, however no (LS) at zero
8
Control word (sy.50); negative set values are set to zero
9
Control word (sy.50); the sign of the set value has no effect
on the direction of rotation
Special Adjustments
Relay output 2
Switching level
This parameter determines the switching point for the relay output 2 (CP.32).
After the switching of the relay, this value can move within a 0.5 Hz window
(hysteresis), without the relay changing states. Since the operator display
can only view 5 characters, the last digits are not displayed for the higher
values.
Adjustment range: -30000.00...30000.00

Hysteresis Levels
Frequency:
