H2 Multi-Function Digital Output Settings
Closed: When the drive output frequency is less than or equal to the value in L4-03 ±L4-04.
Closed: When the output frequency is greater than or equal to the value in L4-03 ±L4-04.
Open: Overtorque or undertorque has been detected.
Closed: Overtorque or undertorque has been detected.
Open: Overtorque or undertorque has been detected.
Closed: Drive is running in the reverse direction.
Open: Drive has entered the baseblock state (no output voltage).
Closed: Motor 2 is selected by a digital input (H1-oo = 16)
Closed: Motor is regenerating energy into the drive.
Closed: An automatic restart is performed
Closed: oL1 is at 90% of its trip point or greater. An oH3 situation also triggers this alarm.
Closed: Mechanical weakening detected.
Closed: Cooling fan, electrolytic capacitors, IGBTs, or the soft charge bypass relay may require
maintenance.
Closed: When the torque limit has been reached.
Closed: Speed limit has been reached.
Closed: Speed limit has been reached while using Torque Control.
Closed: Zero Servo operation has finished.
Open: Either the drive has stopped or baseblock, DC Injection Braking, or Initial Excitation is
being performed.
Closed: Drive is running the motor (not in a baseblock state and DC Injection is not being
performed).
Closed: Multi-function input set for "Drive enable" is closed (H1-oo = 6A)
Output units are determined by H2-06. Outputs a pulse every 200 ms to indicate the kWh count.
Open: REMOTE
Closed: LOCAL
Closed: Speed Search is being executed.
Closed: PID feedback level is too low.
Closed: The PID feedback level is too high.
Closed: KEB Ride-Thru is being performed.
Closed: Short Circuit Braking is active.
Closed: A Fast Stop command has been entered from the operator or input terminals.
Closed: oH pre-alarm time limit has passed.
Closed: The built-in dynamic braking transistor failed.
Note: This function is not available in models CIMR-Ao4A0930 and 4A1200.
Closed: The dynamic braking resistor has overheated.
Note: This function is not available in models CIMR-Ao4A0930 and 4A1200.
Closed: Internal cooling fan alarm
Closed: Drive has successfully detected the rotor position of the PM motor.
Reserved for DWEZ digital output functions.
Inverts the output switching of the multi-function output functions.
Set the last two digits of 1oo to reverse the output signal of that specific function.
