E33 Overload early warning (operation)

E 3 3

O L

L E V E L

Setting range: 0: Electronic thermal O/L relay

Select one of the following two types of overload early
warning: early warning by electronic thermal O/L relay
function or early warning by output current.

1: Output current

Value

Function

Description

0

Electronic
thermal
O/L relay

Overload early warning by electronic thermal
O/L relay (with inverse time characteristics)
to output current. The operation selection and
thermal time constant for the inverse time
characteristics are the same as those of the
electronic thermal O/L relay for motor
protection (F10 and F12).

1

Output
current

An overload early warning is issued when
output current exceeds the set current value
for the set time.

E34 Overload early warning (operation level)

E 3 4

O L 1

L E V E L

Setting range: Drive rated output current x (5 to 150%)

This function determines the operation level for the
electronic thermal O/L relay or output current.

The operation release level is 90% of the set value.

E35 Overload early warning (operation time)

E 3 5

O L

T I M E R

Setting range: 0.0 to 60.0 seconds

This function is used when E33 Overload early warning
(operation selection) is set to 1.

Sets the time from when the operation level is attained
until the overload early warning function is activated.

E36 Frequency detection 2 (operation level)

E 3 6

F D T 2

L E V E L

This function determines the operation (detection) level 2
of the output frequency for operation release. This
function operates the same as “E31 Frequency detection
1 (operation level)”. For details, see the explanation for
E31.

E37 Overload early warning 2
(operationlevel)

E 3 7

O L 2

L E V E L

This function determines the operation level 2 of the
output current. This function operates same as E33
output current and E35 setting.

When the set value is 1, contacts Y5A and Y5C are
connected when the drive control voltage is established
(about one second after power on).

E30 Frequency arrival (detection width)

E 3 0

F A R

H Y S T R

Setting range: 0.0 to 10.0 Hz

This function adjusts the detection width when the output
frequency is the same as the set operating frequency. The
detection width can be adjusted from 0 to

±

10 Hz of the

setting frequency.

When the frequency is within the detection width, an ON
signal can be selected and output from terminals [Y1] to
[Y5]

E31 Frequency detection (operation level)

E32 Frequency detection (hysteresis width)

E 3 1

F D T

L E V E L

E 3 2

F D T

H Y S T R

Setting range (Operation level): 0 to 120 Hz

These functions determine the operation level of the
output frequency and hysteresis width for operation
release. If the output frequency exceeds the set operation
level, an ON signal can be output from terminals Y1 to Y5.

(Hysteresis width): 0.0 to 30.0 Hz
