Drive Enable/Disable; Bypass Drive Enable; Stopping Acceleration And Deceleration (Acceleration/Deceleration Ramp Hold) - Omron VARISPEED E7 User Manual

Drive Enable/Disable

If a digital input is programmed to setting 6A the Inverter can be enabled or disabled by switching the digital
input
If the input is switched OFF while a RUN command is active the inverter will stop using the stopping method
set in b1-03.
The Drive Enable/Disable signal has to be ON before the RUN command is activated.

Bypass Drive Enable

If a digital input is programmed to setting 70 the Inverter will not execute a RUN command until this input is
closed.
Unlike the setting 6A (Drive Enable/Disable) the RUN command does not need to be cycled after closing the
input. The Inverter will start whenever the digital input is closed a RUN command is active with the activated
acceleration time.
If a RUN command is active and the Bypass Drive Enable input is OFF the digital operator shows the alarm
message "dnE".

Stopping Acceleration and Deceleration (Acceleration/Deceleration
Ramp Hold)
• If a digital input is programmed to setting A the Inverter will pause the acceleration or deceleration and
hold the output frequency when the input is closed.
Acceleration/deceleration is restarted when the input is turned OFF.
•
• The motor will be stopped if a stop command is input while the acceleration/deceleration ramp hold input
is ON.
When parameter d4-01 (the frequency reference hold function selection) is set to 1, the held frequency will
•
be stored in memory. This stored frequency will be retained as frequency reference even after a power loss
and the motor will be restarted at this frequency when a run command is input again.
