3. Function Explanation
■
H08 Rev. phase sequence lock
When accidental reversing is expected to cause a malfunction,
this function can be set to prevent reversal.
This function prevents a reversing operation resulting from a
connection between the REV and CM terminals, inadvertent
activation of the
REV
key, or negative analog input from
terminal 12 or V1.
- Set value 0: Inactive
1: Active
■
H09 Start mode (Rotating motor pick up)
This function smoothly starts the motor which is coasting after
a momentary power failure or after the motor has been subject
to external force, without stopping motor.
At startup, this function detects the motor speed and outputs
the corresponding frequency, thereby enabling a shock-free
motor startup. However, the normal startup method is used,
when the coasting speed of the motor is 120Hz or more as an
inverter frequency and when the value set to “F03 Maximum
frequency 1”, exceeds the value set to “F15 Frequency limiter
(High).”
- Set value: 0, 1, 2
Explanation of set values
1: This function is effective when 3, 4, or 5 is set to “F14
Restart mode after momentary power failure .”
This function is also effective when operation is switched
from the line to the inverter.
The motor is started with the same frequency as the
current coasting speed.
2: In addition to restarting following a momentary power
failure and switching between the line and the inverter, this
function detects the coasting speed of the motor and starts
the motor at the same frequency as all startups (including
when an ON operation command is entered).
By assigning value “26 Pick up start mode” to terminals X1 to
X9, this function can be externally selected as the normal
startup method when an ON operation command is entered.
- Set value 0: ON/OFF control disabled.
1: ON/OFF control enabled.
The cooling fan operating status can be monitored from
terminals Y1 to Y5.
■
H07 ACC/DEC pattern (Mode select)
This function selects the acceleration and deceleration
pattern.
- Set value 0: Inactive (linear acceleration and deceleration)
1: S-curve acceleration and deceleration (weak)
2: S-curve acceleration and deceleration (strong)
3: Non-linear (For variable torque load)
[S-curve acceleration and deceleration]
This pattern reduces shock by mitigating output frequency
changes at the beginning/end of acceleration and decelera-
tion.
Pattern constants
* When acceleration and deceleration times are very long or
short, acceleration and deceleration are rendered linear.
[Non-linear acceleration and deceleration]
This function is used to minimize motor acceleration and
deceleration times in the range that includes a constant-output
range.
