2.1.13 Infinitely Variable Change of
Numeric Data Value
If the chosen parameter represents a numeric data value,
select a digit with [
◀
] [
▶
].
Illustration 2.19 Selecting a Digit
Change the selected digit infinitely variably with [
▲
] [
▼
].
The chosen digit is indicated by the cursor. Place the
cursor on the digit to save and press [OK].
2.1.14 Value, Step-by-Step
Certain parameters can be changed step by step or
infinitely varying. This applies to
P-07 Motor Power [kW] ,
F-05 Motor Rated Voltage and F-04 Base Frequency .
The parameters are changed both as a group of numeric
data values and as numeric data values infinitely varying.
2.1.15 Read-out and Programming of
Indexed Parameters
Parameters are indexed when placed in a rolling stack.
ID-30 Fault Log: Error Code to ID-32 Alarm Log: Time contain
a fault log which can be read out. Choose a parameter,
press [OK], and use [
▲
] [
▼
] to scroll through the value log.
Use C-05 Multi-step Frequency 1 - 8 as another example:
Choose the parameter, press [OK], and use [
▲
] [
▼
] to scroll
through the indexed values. To change the parameter
value, select the indexed value and press [OK]. Change the
value by pressing [
▲
] [
▼
]. Press [OK] to accept the new
setting. Press [Cancel] to abort. Press [Back] to leave the
parameter.
2.1.16 Local Control Keys
Keys for local control are found at the bottom of the
keypad.
Illustration 2.20 Keypad Keys
[Hand]
enables control of the frequency converter via the keypad.
[Hand] also starts the motor and it is now possible to enter
the motor speed data by means of the arrow keys. The key
can be selected as
[1] Enable or [0] Disable via K-40 [Hand]
Button on Keypad .
External stop signals activated by means of control signals
or a serial bus will override a 'start' command via the
keypad.
The following control signals are still active when [Hand] is
activated:
•
[Hand] - [Off] - [Auto]
•
Reset
•
Coasting stop inverse
•
Reversing
•
Set-up select lsb - Set-up select msb
•
Stop command from serial communication
•
Quick stop
•
DC brake
[Off]
stops the connected motor. The key can be selected as
[1]
Enable or [0] Disable via K-41 [Off] Button on Keypad .
If no external stop function is selected and the [Off] key is
inactive the motor can be stopped by disconnecting the
voltage.
[Auto]
enables the frequency converter to be controlled via the
control terminals and/or serial communication. When a
start signal is applied on the control terminals and/or the
bus, the frequency converter will start. The key can be
selected as
[1] Enable or [0] Disable via K-42 [Auto] Button
on Keypad .
NOTE
An active HAND-OFF-AUTO signal via the digital inputs has
higher priority than the control keys [Hand] [Auto].
[Reset]
is used for resetting the frequency converter after an alarm
(trip). It can be selected as
[1] Enable or [0] Disable via
K-43 [Reset] Button on Keypad .
