Description
0: Disabled (uses the direction of the
frequency reference)
1: Enabled (drive detects which way the
motor is rotating)
Note: Default setting is
determined by parameter
A1-02, Control Method
Selection.
Sets the Speed Search restart current level
as a percentage of the drive rated current.
Sets the time to detect Speed Search restart.
Sets the number of times the drive can
attempt to restart when performing Speed
Search.
0: Current Detection
1: Speed Estimation
Sets the time the drive must wait between
each Speed Search restart attempt.
Selects a condition to activate Speed Search

function input.
0: Triggered when a Run command is
issued. (normal).
1: Triggered when an external baseblock is
released.
0: Disabled
1: Enabled (PI output becomes output
frequency reference)
3: Enabled (PI output added to frequency
reference)
Sets the proportional gain of the PI
controller.
Sets the integral time for the PI controller.
Sets the maximum output possible from the
integrator as a percentage of the maximum
output frequency.
Sets the maximum output possible from the
entire PI controller as a percentage of the
maximum output frequency.
Applies an offset to the PI controller output.
Set as a percentage of the maximum output
frequency.
Sets a low pass filter time constant on the
output of the PI controller.
0: Normal output (direct acting)
1: Reverse output (reverse acting)
0: Negative PI output triggers zero limit.
1: Rotation direction reverses with negative
PI output.
Note: When using setting 1,
make sure reverse
operation is permitted by
b1-04.

YASKAWA ELECTRIC TOEP C710616 54A YASKAWA AC Drive - Z1000 Quick Start Guide
Description
0: Digital Output Only (Remains active
when PI is disabled by digital input)
1: Alarm output, drive continues operation
(Remains active when PI is disabled by
digital input)
2: Fault output, drive output is shut off
(Remains active when PI is disabled by
digital input)
3: Digital output only. No detection when
PI is disabled by digital input.
4: Alarm detection. No detection when PI is
disabled by digital input.
5: Fault detection. No detection when PI is
disabled by digital input.
Sets the PI feedback loss detection level as
a percentage of the maximum output
frequency.
Sets a delay time for PI feedback loss.
Sets the frequency level that triggers the
sleep/snooze function.
Sets a delay time before the sleep/snooze
function is triggered.
Sets the acceleration and deceleration time
to PI setpoint.
0: Disabled
1: Enabled
Sets the PI target value when b5-18 = 1. Set
as a percentage of the maximum output
frequency.
0: 0.01 Hz units
1: 0.01% units (100% = max output
frequency)
2: r/min (number of motor poles must
entered)
3: User-set (set scaling to b5-38 and b5-39)
Input source selection for Sleep Function
mode.
0: PI Setpoint
1: SFS Input
2: Snooze
Sets the PI Snooze Function start level as a
percentage of the maximum frequency.
Sets the PI Snooze Function delay time in
seconds.
When the PI feedback level drops below
this level, the drive returns to normal
operation. Set as a percentage of the
maximum frequency.
Temporarily increases the PI setpoint to
create an overshoot of the intended PI
setpoint.
Sets the maximum boost time when PI
feedback does not reach boost level.
The Snooze Function starts when the PI
feedback exceeds the boost setting level or
when the boost time expires.
Sets the PI feedback level above which
Snooze mode is activated. Set as a
percentage of the maximum frequency.
0: Disabled
1: Square root
A multiplier applied to the square root of the
feedback.
PI feedback offset set as a percentage of the
maximum frequency.
Sets the minimum output possible from the
PI controller as a percentage of the
maximum output frequency.
