EM330D User Manual
A Special Purpose Inverter for Hoisting
71
Relay output is provided by the internal relay of
inverter.
Relay has 1 set of N/O contacts and 1 set of
N/C contacts. When selected program code is
disabled, EB-EC is N/C, and EA-EC is N/O.
When selected program code is enabled, the coil
of internal relay is power-on, EB-EC is off, and
EA-EC is on, as shown in Figure 7-7.

Description

Inverter Runs
(Enabled at Running)
When inverter is running, the output terminal is on.
1
Frequency Reach Range
FAR(Enabled at running)
If |output frequency–setting input frequency|< the setting value of
F9-11, the output terminal is on.
2
Output Frequency Detection
Range FDT1(Enabled at running)
When inverter is running, if the output frequency increases to the
value of F9-12 (FDT1 Increasing Threshold), the output terminal
is on. If the output frequency drops and is less than the value of
F9-13 (FDT1 Decreasing Threshold), the output terminal is off.
3
Output Frequency Detection
Range FDT2
(Enabled at running)
When inverter is running, if the output frequency increases to the
value of F9-14 (FDT2 Increasing Threshold), the output terminal
is on. If the output frequency drops and is less than the value of
F9-15 (FDT2 Decreasing Threshold), the output terminal is off.
4
Output Frequency Detection
Range FDT1
(Disabled at JOG)
When inverter is running (Except in JOG running mode), if the
output frequency increases to the value of F9-12 (FDT1
Increasing Threshold), the output terminal is on. If the output
frequency drops and is less than the value of F9-13 (FDT1
Decreasing Threshold), the output terminal is off.
5
Output Frequency Detection
Range FDT2
(Disabled at JOG)
When inverter is running (Except in JOG mode), if the output
frequency increases to the value of F9-14 (FDT2 Increasing
Threshold), the output terminal is on. If the output frequency
drops and is less than the value of F9-15 (FDT2 Decreasing
Threshold), the output terminal is off.
6
Forward/Reverse
(Enabled at Running)
When inverter is running, if the motor reverses, the output
terminal is on. If the motor forwards, the output terminal is off.
7
Frequency Input/Output Balance
(Enabled at Running)
When inverter is running, if output frequency= the setting
frequency, the output terminal is on.
8
JOG
When inverter is jogging, the output terminal is on.
9
Inverter Fault
When inverter trips fault, the output terminal is on.
10
Upper Limit Frequency
Reach(Enabled at Running)
When the output frequency of inverter reaches the setting upper
limit frequency of F0-17, the output terminal is on.
11
Lower Limit Frequency
When the output frequency reached the lower limit frequency set
