Function
Operation when the motor
temperature analog input (H03-02,
H03-06, or H03-10 = E) exceeds
the OH3 alarm level. (1.17V)
Decel by B05-08
OH3 Flashes
Operation when the motor
temperature analog input (H03-02,
H03-06, or H03-10 = E) exceeds
the OH4 fault level. (2.34V)
Decel by B05-08
Motor temperature analog input
filter time constant (H03-02, H03-
