Description
T0
Delay time from the main power is off to the switch of emergency power
input contactors
KM3 and KM4
are on
T1
Delay time from the time when the inverter receives the run signal to the
time when the inverter outputs contactor actuation command
T2
Wait delay time from the time when the inverter outputs contactor
actuation command to the time when the inverter receives the contactor
feedback signal
T3
Relay time from the time when the run command is sent to the time when the
run signal is output
T4
Delay time from the time when the run signal is output to the time when the
brake open signal is sent.
T5
Interval from the brake open command sending time to the feedback time of
brake open.
T6
(Brake close delay time)
T7
Wait delay time from the time when the inverter outputs the brake close
command to the time when the inverter receives the stop command from the
external controller
T8
Inverter stop delay time
T9
(Contactor switch-off delay)
After the main circuit power is off, contactor B is switched off first. Before the bus voltage decreases to
300V, contactor A and contactor C are switched on.
1.
When the main power is off, the controller cuts off main power relay (KM1), after T0, the control
switch of emergency power will be closed, and output emergency command at the same time ,
after T1, the inverter receives the running command (FWD/REW) from the controller.
2.
Then after T2, the inverter detects the contactor actuation command signal, and then the
inverter starts to run at zero speed, at the same time outputs running signal (Y1). After T4, the
inverter outputs brake release signal.
3.
After T5, the inverter receives brake feedback signal, after affirming the brake is released
completely, the inverter accelerates with emergency acceleration time (
) to reach to
emergency speed (
), and then runs at a constant speed.
4.
When the lift runs to the flat floor, the controller will cut off emergency command (EMER), and
the inverter begins to decelerate to stop with emergency deceleration (
), when the
inverter decelerates to
, after T6, the inverter outputs brake close command, and
requires the controller to cut off running command.
5.
After T7, the inverter receives stop command, and then after the delay time of T8 and T9, the
