*1: Access Level (A1-01): Q = “Quick Start”, A = “Advanced”, F = “Factory”.
*2: Unit and scaling based on O1-03 (Display Scaling) setting. When O1-03 ≥ 40 (custom units), the displayed
units on the keypad are determined by parameter P2-09.
*3: Unit and scaling based on P2-10 (Output Monitor Units) setting. Parameter P2-10 operates exactly the same
way as O1-03. When P2-10 ≥ 40 (custom units), the displayed units on the keypad are determined by
parameter P2-09.

Valve
Closed: Drive has received a run command, the P2-08 delay
timer has expired, and the PID feedback high detection
function is not on (level set in P1-02). Opens immediately
after the run command is removed or the PID feedback high
detection function is satisfied.
