AC70 VC CONTROL FREQUENCY INVERTER MANUAL
FUNCTION PARAMETER DETAILED SPECIFICATION

button of keypad.
10: Program running
Main frequency given and rotation direction of inverter are configured by inverter’s inner
simple PLC process control. Up to 8 steps speed control is available, refer to
[E-13, E-14, F-09-F-16, F-24-F-29,
H-32-H-52]
Tips: Frequency main channel and frequency auxiliary channel can be set the same channel. In this case,
the corresponding relationships between the frequency setting values and input signal are rather special, it
need to consider the frequency main channel and auxiliary channel both characteristic at the same time.
The combination of main and auxiliary frequency given still limited by upper frequency limit and lower
frequency limit.
E-04
Frequency reference given
channel gain
Range:0.01-5.00
Default:1.00
E-05
Frequency reference given
channel combination mode
Range:0-10 Default:
0
Frequency reference given channel gain:
Uses to amplify or lessen the frequency input channel signal.
Proportional regulating of frequency given both main and auxiliary channel is available.
Frequency given channel combination mode
: Uses for selecting frequency given main channel and auxiliary
channel combination. K stands for
[E-04]
setting value, MAX means takes the bigger among the both channel, MIN
means takes the smaller among the both.
0:Main channel is valid, auxiliary channel is invalid.
1:Auxiliary channel valid, main channel invalid
2:Both channel non “0” value valid, main channel priority
3:Main c ( K × auxiliary channel
)
4:Main channel -
(
K × auxiliary channel
)
5:MAX [main channel , (K × auxiliary channel)]
6:MIN [main channel , (K × auxiliary channel)]
7:Auxiliary c (K × main channel)
8:Auxiliary channel - (K × main channel)
9:MAX [(K × main channel), auxiliary channel]
10: MIN [(K × main channel), auxiliary channel]
Tips: 1. Terminal (VS2) will be quite special in the multi-channel combination case.
A. When (VS2) terminal don not activate the bipolarity adjustment and direct control function both (
[F-48]
set to 0),
the combination mode determined
[E-05]
combination mode setting.
B. When (VS2) terminal activate the bipolarity adjustment and direction control function both (
[F-48]
set to 1 ),
( VS2 ) terminal frequency given with bipolarity and frequency given in another channel implement signed arithmetic
based on the combination mode selected, the absolute value is for frequency given, the signed determine the
direction rotation of motor after calculation.
C. When (VS2) activate the bipolarity adjustment but no direction control. (
[F-48]
set to 2 ). ( VS2 ) terminal
frequency given with bipolarity and frequency given in another channel implement signed arithmetic based on the
combination mode selected, the absolute value is for frequency given, the rotation direction depend on the
[E-01]
Running control command selection.
2. Swing frequency running, jog function and multi-step is disabled combine with auxiliary channel.
E-06
Upper LED monitor selection
Range:0-7
Default:0
E-07
Lower LED monitor selection
Rang:0-7
Default:1
Uses to select the monitoring items displayed in two LED on the keyboard respectively. In the monitoring status, the
upper LED monitoring item and the lower monitoring item can be modify directly via SET key and SHIFT key.
0: Frequency reference Given 1: Output frequency 2: Output current 3: Input voltage
4: Output voltage 5: Machine speed 6: PID given 7: PID feedback value
When there is only one LED on the keyboard, it is disable to modify the lower LED monitoring via the
[E-07]
and
SHIFT key.
