Figure 5.33 During Frequency Output Time Chart
Setting 39: Watt Hour Pulse Output
Outputs a pulse to indicate the watt hours.
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 100 to 160: Functions 0 to 60 with Inverse Output
These settings have the same function as settings 0 to 60, 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”.

H3: Multi-Function Analog Inputs
The drive is equipped with multi-function analog input terminals: A1 and A2.
Refer to Multi-Function Analog Input Terminal
for a listing of the functions that can be set to these terminals.

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.

Setting 0: 0 to 10 V with Zero Limit
The input level is 0 to 10 Vdc with zero limit. The minimum input level is limited to 0%, so that a negative input signal due
to gain and bias settings will be read as 0%.
