5.11 S: Functions for Textile Applications
YASKAWA ELECTRIC SIEP C710616 30B YASKAWA AC Drive T1000A Technical Manual 251
Parameter Details
5
• KEB is triggered.
• The drive detects power loss.
n
S1-01: Disturb Function Selection
Enables or disables the Disturb function. If enabled, the Disturb waveform is generated when the frequency reference
and output frequency match (referred to as "speed agree").
Setting 0: Disabled
Setting 1: Enabled
Setting 2: Enabled, Outputs the Disturb Waveform During Accel/Decel
n S1-02: Disturb Function Amplitude
Sets the amplitude of the Disturb waveform as a percentage of the frequency reference.
n
S1-03: Disturb Step
Sets the step applied at the end of disturb acceleration or deceleration as a percentage of the Disturb amplitude in S1-02.
n
S1-04: Disturb Deceleration Time
Sets the deceleration time for the Disturb function.
n
S1-05: Disturb Acceleration Time
Sets the acceleration time for the Disturb function.
u S2: Frequency Reference Gain Settings
Independent of the frequency reference source selected, this function applies a gain to the frequency reference value. A
gain change ramp can be used in order to avoid speed steps when the gain value in S2-02 is modified.
n
S2-01: Frequency Reference Gain
Determines how much to reduce or amplify the frequency reference. Note that the frequency reference cannot exceed the
upper limit set to d2-01, regardless of how high S2-01 is set.
n
S2-02: Frequency Reference Gain Change Ramp
Determines the time the drive uses to change the frequency reference gain from 0.0% to the value assigned to S2-01.
