U4-05

(007C)

CapacitorMaintenance

Shows the operation time of the electrolytic capacitors for the main circuit and control circuit as a
percentage of the replacement life of the electrolytic capacitors.

Use parameter

o4-05 [Capacitor Maintenance Setting]

to reset this monitor.

Unit: 1%

Note:

Replace the electrolytic capacitor when this monitor is 90%.

10 V: 100%

U4-06

(07D6)

PreChargeRelayMainte

Shows the operation time of the soft charge bypass relay as a percentage of the replacement life of
the soft charge bypass relay.

Use parameter

o4-07 [Softcharge Relay Maintenance Set]

to reset this monitor.

Unit: 1%

Note:

Replace the drive when this monitor is 90%.

10 V: 100%

U4-07

(07D7)

IGBT Maintenance

Shows the operation time of the IGBTs as a percentage of the replacement life of the IGBTs.

Set parameter

o4-09 [IGBT Maintenance Setting]

to reset this monitor.

Unit: 1%

Note:

Replace the drive when this monitor is 90%.

10 V: 100%

U4-08

(0068)

Heatsink Temperature

Shows the heatsink temperature of the drive.

Unit: 1 °C

10 V: 100 °C

U4-09

(005E)

LED Check

Turns on the LED Status Ring and all of the keypad LEDs to make sure that the LEDs operate
correctly.

Set

o2-24 = 0 [LED Light Function Selection = Enable Status Ring & Keypad LED]

Push

with

U4-09

shown on the keypad.

All LEDs on the keypad and LED Status Ring will turn on.

Note:

When Safety input 2 CH is open (STo), READY will flash.

U4-10

(005C)

kWh, Lower 4 Digits

Shows the lower 4 digits of the watt hour value for the drive.

Unit: 1 kWh

Note:

The watt hour is displayed in 9 digits. Monitor

U4-11 [kWh, Upper 5 Digits]

shows the upper 5

digits and

U4-10

shows the lower 4 digits.

Example for 12345678.9 kWh:

U4-10

678.9 kWh

U4-11

12345 MWh

No signal output available

U4-11

(005D)

kWh, Upper 5 Digits

Shows the upper 5 digits of the watt hour value for the drive.

Unit: 1 MWh

Note:

Monitor

U4-11

shows the upper 5 digits and

U4-10 [kWh, Lower 4 Digits]

shows the lower 4

digits.

Example for 12345678.9 kWh:

U4-10

: 678.9 kWh

U4-11

: 12345 MWh

U4-13

(07CF)

Peak Hold Current

Shows the hold value of the peak value (rms) for the drive output current.

Use

U4-14 [PeakHold Output Freq]

to show the drive output frequency at the time that the drive

holds the output current.

The drive will hold the peak hold current at the next start up and restart of the power supply.

The drive keeps the held value during baseblock (during stop).

The keypad shows the value of

U4-13

in amperes (A). When you use serial communications to show

the monitor, the current is

“

8192 = drive rated current (A).

”

Use the formula:

“

Numerals being

displayed / 8192 × drive rated current (A)

”

to use the serial communication current value shown in

the monitor.

Unit: Determined by the drive model.

•

0.01 A: 2011 to 2046, 4005 to 4014

•

0.1 A: 2059 to 2273, 4021 to 4302

No signal output available

U4-14

(07D0)

PeakHold Output Freq

Shows the output frequency at which the peak value (rms) of the drive output current is held.

The peak hold current can be monitored by

U4-13 [Peak Hold Current]

The peak hold output frequency will be cleared at the next startup and restart of the power supply.
The drive keeps the value that was under hold during baseblock (during stop).

Unit: 0.01 Hz

No signal output available

U4-16

(07D8)

Motor oL1 Level

Shows the integrated value of

oL1 [Motor Overload]

as a percentage of

oL1

detection level.

Unit: 0.1%

10 V: 100%
