Application Notes
13-33
Acceleration and deceleration are not affected by the skip frequencies. Normal
accel/decel will proceed through the band once the commanded frequency is greater
than the skip frequency. See (A) & (B) in Figure 13-15. This function affects only
continuous operation within the band.
13.15 Sleep Wake Mode
This function stops (sleep) and starts (wake) the drive based on separately
configurable analog input levels rather than discrete start and stop signals. When
enabled in “Direct” mode, the drive will start (wake) when an analog signal is greater
than or equal to the user specified Wake Level (180), and stop the drive when an
analog signal is less than or equal to the user specified Sleep Level (182). When
Sleep Wake is enabled for “Invert” mode(1), the drive will start (wake) when an analog
signal is less than or equal to the user specified Wake Level (180), and stop the drive
when an analog signal is greater than or equal to the user specified Sleep Level (182).
Skip Frequency Examples
The skip frequency will have hysteresis so the
output does not toggle between high and low
values. Three distinct bands can be
programmed. If none of the skip bands touch or
overlap, each band has its own high/low limit.
If skip bands overlap or touch, the center
frequency is recalculated based on the highest
and lowest band values.
If a skip band(s) extend beyond the max
frequency limits, the highest band value will be
clamped at the max frequency limit. The center
frequency is recalculated based on the highest
and lowest band values.
If the band is outside the limits, the skip band is
inactive.
