Selects which parameters are accessible via
the HOA keypad.
0: Operation only. A1-01, A1-04, and
A1-06 can be set and monitored, and
Uo-oo parameters can also be viewed.
1: User Parameters. Only parameters
A1-00, A1-01, and A1-04, and A2-01 to
A2-32 in Setup Mode can be set and
monitored.
2: Advanced Access Level. All
parameters can be set and monitored.
0: V/f Control
5: Open Loop Vector Control for PM
0: No initialization
1110: User Initialize (parameter values
must be stored using parameter o2-03)
2220: 2-Wire Initialization
3330: 3-Wire Initialization
3410: HVAC Initialization
3420: OEM Bypass Initialization
When the value set into A1-04 does not
match the value set into A1-05, parameters
A1-01 through A1-03, A1-06, and A2-01
through A2-32 cannot be changed.

Parameters selected by the user are saved
as User Parameters, including changed
parameters and parameters specifically
selected for quick access.
If parameter A2-33 is set to 1, changed
parameters will be listed between A2-17
and A2-32. Parameters A2-01 through
A2-16 must be manually selected by the
user.
If A2-33 is set to 0, recently viewed
parameters will not be saved to the group of
User Parameters. A2-oo parameters are
now available for manual programming.

YASKAWA ELECTRIC TOEP C710636 11E Z1000U HVAC MATRIX Drive Quick Start Guide
Description
0: Standard
1: Switch phase order (reverses the
direction of the motor)
0: Disregarded
A new Run command must be issued after
power up.
1: Allowed
Motor will start immediately after power up
if a Run command is already enabled.
Sets the frequency at which DC Injection
Braking starts when "Ramp to stop" (b1-03
= 0) is selected.
Sets the DC Injection Braking current as a
percentage of the drive rated current.
Sets DC Injection Braking time at start.
Disabled when set to 0.00 seconds.
Sets DC Injection Braking time at stop.
Determines the percentage of motor rated
output current used for the motor pre-heat
function.
0: Disabled
1: Enabled
Note: Default setting is dependent upon
parameter A1-02, Control Method
Selection.
Sets the current level at which the speed is
assumed to be detected and Speed Search is
ended. Set as a percentage of the drive rated
current.
Sets output frequency reduction time
during Speed Search.
Determines how much to lower the V/f ratio
during Speed Search.
Output voltage during Speed Search equals
the V/f setting multiplied by b3-04.
When using an external contactor on the
output side, b3-05 delays executing Speed
Search after a momentary power loss to
allow time for the contactor to close.
Sets the current injected to the motor at the
beginning of Speed Estimation Speed
Search. Set as a coefficient for the motor
rated current.
Sets the gain which is applied to the speed
detected by Speed Estimation Speed Search
before the motor is reaccelerated. Increase
this setting if ov occurs when performing
Speed Search after a relatively long period
of baseblock.
0: Disabled (uses the direction of the
frequency reference)
1: Enabled (drive detects which way the
motor is rotating)
Note: Default setting is dependent upon
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.
