7. FR pin function and I
2C serial data excitation direction setting
[FR pin]
Using the FR1 (FR2) forward/reverse rotation setting signal input pin, it is possible to switch the excitation direction
between forward and reverse rotation.
When FR is set to low, the clockwise (CW: forward rotation) direction is set; conversely, when it is set to high, the
counterclockwise (CCW: reverse rotation) direction is set.
In CW (forward rotation) mode, the channel 2 (channel 4) current phase is delayed by 90° relative to the channel 1
(channel 3) current.
In CCW (reverse rotation) mode, the channel 2 (channel 4) current phase is advanced by 90° relative to the channel 1
(channel 3) current.
[I2C serial data excitation direction setting]
When the excitation (rotation) direction of the stepping motor is determined using the “excitation direction” setting, the
output is switched to forward or reverse rotation at the rising edge of the 8th bit of SCL in the data transmission.
In CW (forward rotation) mode, the channel 2 (channel 4) current phase is delayed by 90° relative to the channel 1
(channel 3) current.
In CCW (reverse rotation) mode, the channel 2 (channel 4) current phase is advanced by 90° relative to the channel 1
(channel 3) current.
* Since the FR1 (FR2) forward/reverse signal input pins are provided with an internal pull-down resistor, these pins are
set to the low state when they are open. Furthermore, when these pins are set to low, the excitation direction setting
established using an I2C serial data communication takes priority. Conversely, when they are set to high, the excitation
direction is always set to “reverse rotation” regardless of the I2C communication setting.
