 Drive Enable/Disable
If a digital input is programmed for this function (H1-=6A) the drive can be enabled or disabled by
switching the digital input ON/OFF (ON – Drive enabled).
If the input is switched OFF while a RUN command is active the inverter will stop using the stopping method
set in b1-03.
 Stopping Acceleration and Deceleration (Acceleration/Deceleration
Ramp Hold)
• A multi-function input can be used to pause the acceleration or deceleration and maintain (hold) the output
frequency. To program one digital input for this function one of the parameters H1-01 to H1-05 has to be
set to 6A.
• The acceleration/deceleration is hold when the input is turned ON.
• The acceleration/deceleration is restarted when the acceleration/deceleration ramp hold 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.
