FR500A&FR510A Series Vector Control Inverter
- 93 -
switched to keypad
control
terminal status is switched from OFF to ON, run command will
be switched to keypad control.
30
Run command
switched to terminal
control
This terminal should be enabled by trigger edge. When this
terminal status is switched from OFF to ON, run command will
be switched to terminal control.
31
Run command
switched to
communication
control
This terminal should be enabled by trigger edge. When this
terminal is switched from OFF to ON, run command will be
switched to communication control.
32
Count input
The maximum frequency at count pulse input terminal is
200Hz, and the count value can be memorized in case of
power loss. With the setting of F14.07 (set count value) and
14.08 (designated count value), this terminal can control
digital output “set count value attained” and “designated count
value attained”.
33
Count clear
Used with “count input” terminal, to clear pulse count value.
34
Length count
It is used for fixed-length control, and only takes effect on
digital input terminal DI7/HI. The length is calculated via
pulse input. Please refer to specification of parameters
14.04
～
F14.06 for details. When the length is attained, digital
output terminal “length attained” shall output effective signal.
The current length value will be memorized on power loss.
35
Length clear
Used with “length count” terminal, to clear the length
calculated.
36
DC brake input
command at stop
When inverter is in the process of ramp-to-stop, and running
frequency < DC brake frequency (Set by F02.13) at stop, if the
terminal is ON, DC brake starts, until the terminal is OFF, DC
brake ends.
If the terminal is ON, and DC brake setting time is effective,
take the bigger value between time when terminal is ON and
DC brake setting time at stop.
37
Speed/torque
control switch
When motor control mode is sensor-less vector control 2 and
inverter stop, inverter will switch from speed control mode to
torque control mode if this function is valid
38
No reverse
If this function is valid, the motor can’t reverse.
39
No forward
If this function is valid, the motor can’t forward
40
Zero-serve
Zero servo enabled terminal is only valid with PG vector
control mode, and F21.00 (position control mode selection)
needs to be set to 2:zero servo (terminal valid).
41
Enable spindle
orientation
The spindle orientation function is only effective with PG
vector control mode, and F21.00 (position control mode
selection) needs to be set to 3: spindle orientation.
When inverter is in operation, if it receives the effective
signal of the " Enable spindle orientation " terminal, it reduces
the output frequency according to the set deceleration time.
When the motor speed reaches the directional speed, it
detects the Z signal of the encoder, then decelerates and
stops the machine according to the set directional deceleration
time, and finally stops at the set directional position.
42
Spindle Orientation
Position Selection 1
Through the state combination of the two input terminals,
the switch can be made between four directional positions. For
details, please refer to F21 group spindle orientation function
instructions
43
Spindle Orientation
Position Selection 2
44
Simple carry origin
signal input
This function only valid in PG vector control mode, and
F21.00 (position control mode selection) is set to 4. When the
simple carry control seeks the origin, this terminal signal is
used as the input of the origin signal. The terminal input is ON
at the origin position and OFF at the non-origin position
