6.9.2. Enable error map
After setting the related parameter of error map described above, the drive has the ability of
error compensation. As soon as the motor completes the homing procedure, the drive starts
the error map immediately. There are two ways for D2 drive to complete the homing
procedure. Just choose one of them to use.
(1) Homing with host controller
First, set the input function of “Home Ok, start err. map” in the I/O center (see Section
5.5). Assume that this function is set to I2, as shown in Fig. 6-64. The host controller
sends the motion command to the drive via the pulse command or voltage command to
let the motor move to the home position. Then, it stops to send the motion command. The
host controller must send the signal to I2 through its digital control output. At this time, if
the drive receives this signal, it thinks that the homing procedure is completed and starts
the error map function.

(2) Stand-Alone homing
Go to the performance center and click the “Home” button ( ) to execute the
homing procedure (see Section 6.2).
How to confirm whether the error map function is enabled
At any time, if users want to confirm whether the error map function is already in use, go to the
“Status” area in the “Error map” window, and observe whether the “error map active” light is
green. The green light indicates that the error map function is enabled.
6.9.3. Save/open error map
The established error compensation value can be directly saved into the disk, and can also be
directly read from the disk. As shown in the following figure, click “File” in the function menu to
do it. As described in Section 6.9.1, the “Send Table to Flash” option of “Files” in the function
menu can save the error map table in the drive’s Flash. Note that, the “Save to Flash” button
( ) in the main window cannot automatically save the error map table in the drive’s Flash
