AC70 VC CONTROL FREQUENCY INVERTER MANUAL
FUNCTION PARAMETER DETAILED SPECIFICATION
80
Note: The frequency output is 0 when the frequency given less than starting frequency during the
acceleration process.

LED unit digit: Starting mode selection.
0: Starts from starting frequency
Inverter starts with
[E-28]
starting frequency given and
[E-29]
starting
frequency holding time given. Applicable for application which has big static friction torque, light load inertia, Or suit
to work together with machinery that equipped external mechanical braking. That is occasion where the shaft of
motor can maintain still before start, but after motor stop.
1: DC braking first, and then start from starting frequency
Perform DC braking function first with DC braking
voltage
[E-35]
and DC braking time
[E-38]
to feed motor a center DC braking energy (Electromagnetic braking),
and then starts with starting frequency. Applicable for occasion there are forward or reverse running of small inertia
load in stop status.
2: Restart after speed searching
Inverter try to detect the speed of a rotating motor shaft that is driven by
external forces first and start the motor operation directly from the detected speed to frequency given according
acceleration /deceleration time.
Note: During forward/reverse switching process in normal operation, and perform accel/decel process
after frequency given modifying, both start from 0.0Hz or stop to 0.0Hz.
LED tens digit: Reserve
LED hundreds digit: Speed search direction
0: Speed search performs only in running direction
1: Bi-speed search performs
LED thousands digit: Speed search mode
0: Software speed search
1: Hardware speed search
