*1. In DACA-, the reversed voltage of the DACA+ is output. In other words, when DACA+ = +10 V, then DACA-
= -10 V. In this case, between DACA+ and DACA-, a 20 V potential difference is generated. The same ap-
plies to DACB+/DACB-.
*2. Available with the CK3W-AX1414£/1515£ Units.
*3. For connection with a Servo Drive with 5-VDC photocoupler input, only CK3W-AX1414£/-AX1515£ Units
whose date of production is July 1, 2019 or later (Lot number 01719K and later) are available.

DA Output Method

The following two methods are available for DA output.
• FilteredPWM
• TrueDAC
This section describes each of the methods.
FilteredPWM
This is a method for creating analog output by smoothing the PWM pulse.
The relationship between the set value and output voltage is shown below.
