YASKAWA ELECTRIC TOEP C710636 11E Z1000U HVAC MATRIX Drive Quick Start Guide
Description
Sets the number of times the drive can
attempt to restart when performing Speed
Search.
1: Speed Estimation
2: Current Detection 2
Note: Default setting is dependent upon
parameters A1-02, Control Method
Selection, and o2-04, Drive Model
Selection.
Sets the time the drive must wait between
each Speed Search restart attempt.
0: Triggered when a Run command is
issued. (normal).
1: Triggered when an external baseblock is
released.
0: Disabled
1: Enabled (PID output becomes output
frequency reference)
3: Enabled (PID output added to frequency
reference)
Sets the proportional gain of the PID
controller.
Sets the maximum output possible from the
integrator as a percentage of the maximum
output frequency.
Sets D control derivative time.
Sets the maximum output possible from the
entire PID controller as a percentage of the
maximum output frequency.
Applies an offset to the PID controller
output. Set as a percentage of the maximum
output frequency.
Sets a low pass filter time constant on the
output of the PID controller.
0: Normal output (direct acting)
1: Reverse output (reverse acting)
Sets the gain applied to the PID output.
0: Negative PID output triggers zero
limit.
1: Rotation direction reverses with negative
PID output.
Note: When using setting 1, make sure
reverse operation is permitted by b1-04.
0: Digital Output Only
(Remains active when PID is disabled by
digital input)
1: Alarm output, drive continues operation
(Remains active when PID is disabled by
digital input)
2: Fault output, drive output is shut off
(Remains active when PID is disabled by
digital input)
3: Digital output only. No detection when
PID is disabled by digital input.
4: Alarm detection. No detection when PID
is disabled by digital input.
5: Fault detection. No detection when PID
is disabled by digital input.
Sets the PID feedback loss detection level
as a percentage of the maximum output
frequency.
Sets a delay time for PID feedback loss.
Sets the frequency level that triggers the
sleep/snooze function.

Description
Sets the acceleration and deceleration time
to PID setpoint.
1: Enabled
Sets the PID 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: PID Setpoint
1: SFS Input
2: Snooze
Sets the PID Snooze Function start level as
a percentage of the maximum frequency.
Sets the PID Snooze Function delay time in
seconds.
When the PID feedback level drops below
this level, the drive returns to normal
operation. Set as a percentage of the
maximum frequency.
Temporarily increases the PID setpoint to
create an overshoot of the intended PID
setpoint.
Sets the maximum boost time when PID
feedback does not reach boost level.
The Snooze Function starts when the PID
feedback exceeds the boost setting level or
when the boost time expires.
Sets the PID 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.
PID feedback offset set as a percentage of
the maximum frequency.
Sets the minimum output possible from the
PID controller as a percentage of the
maximum output frequency.
Limits the PID control input (deviation
signal) as a percentage of the maximum
output frequency. Acts as a bipolar limit.
Sets the PID feedback high detection level
as a percentage of the maximum output
frequency.
Sets the PID feedback high level detection
delay time.
Sets the display value of U5-01 and U5-04
when the maximum frequency is output.
0: No decimal places
1: One decimal place
2: Two decimal places
3: Three decimal places
Note: Default setting is dependent upon
parameter b5-20, PID Setpoint Scaling.
0: Display the frequency reference (U1-01)
after PID compensation has been added.
1: Display the frequency reference (U1-01)
before PID compensation has been added.
