Chapter 12 Inverter Functions
Example of the Control on the Secondary Side
(AF120 = 02: Enabled (secondary side)
• When Enabled (secondary side) is selected, using in
combination with the brake control 2 is available.
Once the operation command is received, the
inverter turns on
the control signal 039[CON].
The operation varies depending on whether the
contactor check signal 112[COK] is set to the
input terminal function.
With
[COK]
setting
The inverter turns on the control signal
039[CON] and, if the 112[COK] is not turned on
during the contactor check time, the inverter
trips with the [Er110] contactor error.
Without
[COK]
setting
After the control signal 039[CON] is turned on,
there is a waiting time for the start waiting time
to pass.
The inverter starts the output and is in the servo
lock status at the present location
for the servo lock time at start.
After the brake release delay time passes, the
brake release signal 037[BRK] is turned on.
The operation varies depending on whether the
brake check signal 037[BOK] is set to the input
terminal function.
With
[BOK]
setting
If the 037[BOK] is not turned on during the
brake check waiting time, the inverter trips with
the [E036] brake error outputting the fault
signal 038[BER].
Without
[BOK]
setting
After the release signal 037[BRK] signal is
turned on, there is a waiting for the servo lock
time at start to pass.
After the servo lock time at start passes, there is
an acceleration.
Once the operation command is turned off, the
inverter decelerates and is in the position servo
lock status for the servo lock time at stop.
After the brake release delay time passes, the
brake release signal 037[BRK] is turned off.
The operation varies depending on whether the
brake check signal 037[BOK] is set to the input
terminal function.
With
[BOK]
setting
The inverter turns off the release signal
037[BOK], and if the 037[BOK] is not turned off
during the brake check time, the inverter trips
with the [E036] brake error outputting the fault
signal 038[BER].
Without
[BOK]
setting
After the release signal [BRK] signal is turned
off, there is a waiting for the servo lock time at
stop to pass.
The inverter shuts off the output and, after the
contactor release delay time passes, the
control signal 039[CON] is turned off.
The operation varies depending on whether
the contactor check signal 112[COK] is set to
the input terminal function.
With
[COK]
setting
If the 112[COK] is not turned off during the
contactor check time, the inverter trips with the
[E110] contactor error.
Without
[COK]
setting
The inverter still does nothing.
