Setting 38: Drive Enable
Reflects the status of a digital input configured as a “Drive enable” input (H1-oo = 6A). If that digital input closes, then the
digital output set for “Drive enable” will also close.
Setting 39: Energy Pulse Output
Outputs a pulse to indicate the watt hours.
Setting 3A: Regen Pulse Output
Outputs a pulse to indicate the regenerated power.
Setting 3D: During Speed Search
The output terminal closes while Speed Search is being performed.
Setting 4C: During Fast Stop
The output terminal closes when a Fast Stop is being executed. .
Setting 4D: oH Pre-Alarm Time Limit
The output terminal closes when the drive is reducing the speed due to a drive overheat alarm (L8-03 = 4) and the overheat
alarm has not disappeared after 10 frequency reduction operation cycles.
Setting 60: Internal Cooling Fan Alarm
The output closes when the drive internal cooling fan has failed.
Setting 64: During Commercial Power Operation
Output closes when operating on commercial power when commercial power switching is selected (b1-24 = 1).
Setting 100 to 164: Functions 0 to 64 with Inverse Output
These settings have the same function as settings 0 to 64, but with inverse output. Set as 1oo, where the “1” indicates inverse
output and the last two digits specify the setting number of the function.
Examples:
• Set 108 for inverse output of “8: During Baseblock 1 (N.O.)”.
• Set 14D for inverse output of “4D: oH Pre-Alarm Time Limit”.
u H3: Multi-Function Analog Inputs
The drive is equipped with multi-function analog input terminals A1, A2, and A3. Refer to Multi-Function Analog Input
Terminal Settings on page 178 for a listing of the functions that can be set to these terminals.
n H3-01: Terminal A1 Signal Level Selection
Selects the input signal level for analog input A1. Set jumper S1 on the terminal board accordingly for voltage input or current
input.
