Description
Used to set the time to perform DC
injection braking at stop in units of
1 second.
Used to prevent coasting after the
stop command is input. When the
set value is 0.00, DC injection
braking at stop is not performed.
Sets the time delay from the brake
open command to the start of
acceleration.
This timer can be used to avoid
running against the closed brake at
start.
Sets the time delay from the inter-
nal brake close command until the
brake control output is switched.
This timer can be used to avoid
closing the brake when the motor is
still turning.
Used to set the delay time for the
detection of a SE2 fault.
At the time S1-06 + S1-14 after the
Fwd/Rev command was given the
output current is measured. If it is
below 25% of the no-load current
(E2-03) setting a SE2 fault will be
output.
Used to set the delay time for the
detection of a SE3 fault.
At the time S1-15 after the fwd/rev
command was given, the inverter
starts to observe the output current
continuously. If it falls below 25%
of the no-load current (E2-03) set-
ting a SE3 will be output.
Sets the delay time from the Run
signal input to the internal run
enable.
Used to set the DC injection gain
when inverter is in the regenerative
mode.
Used to set the DC injection gain
when inverter is in the motoring
mode.
Sets the contactor control output
delay time after stop.
