*2. Hysteresis for Frequency Detection 2 can be adjusted by changing the frequency detection width (L4-02) between 0.0 and 0.5 Hz. If the load slips during stop, make incremental changes
of 0.1 Hz until the load no longer slips.

Sequence Circuit Design
The braking sequence should be designed as follows:
• The brake should release when terminal P2-PC closes in response to the run conditions on the sequence side
• When a fault signal is output, the brake should close. When an Up or Down command is entered, the brake should release.
Timechart
A sequence to open and close the holding brake appears in the diagram below.
When changing the speed using an analog signal, make sure that the source of the frequency reference is assigned to the control circuit terminals (b1-01
= 1).

A1-07: DriveWorksEZ Function Selection
DriveWorksEZ is an independent software package that can be used to operate and monitor the drive with a 2 ms scan. It is fully compatible with all types
of serial communication software available on the market.
Setting A1-07 to 1 allows the drive to connect to the DriveWorksEZ software package. When using DriveWorksEZ, be sure to set one of the multi-function
terminal inputs for DrivesWorksEZ (H1-oo = 9F). The drive is ready to communicate with the software when the terminal is open. Set A1-07 to “0”
when DriveWorksEZ is not used.
Please remember that if DriveWorksEZ assigned functions to the multi-function output terminals (both analog and digital), that the terminals will still be
set to those functions even after DriveWorksEZ is disabled or disconnected.
Note: For more information on DriveWorksEZ, contact a Yaskawa representative or the Yaskawa sales department directly.

A2-01 to A2-32: Preferred Parameters
The user can select 32 parameters and set them to A2-01 through A2-32. This saves time later scrolling through the parameter menu. The list of Preferred
Parameters can also be used to keep track of the most recently edited settings, saving those parameters to this list.

A2-01 to A2-32 Preferred Parameters 1 to 32 b1-01 to o2-08 A1-06
Detailed Description
To save specific parameters to A2-01 to A2-32, the user must first set the access level to allow access to all parameters (A1-02 = 2). After selecting which
parameters should be saved and setting those parameters to A2-01 through A2-32, the access level can then be set to allow access only to the selected list
of Preferred Parameters. To restrict access so that users can only set and reference the specific parameters saved as Preferred Parameters, set A1-01 to
“1”.

A2-33: Preferred Parameter Automatic Selection
A2-33 determines whether or not parameters that have been edited are saved to the Preferred Parameters (A2-17 to A2-32) for quick, easy access.
