2.15 Monitor display and monitor output signal
2.15.1 Speed display and speed setting [Pr. 37, 144*, 505*, 811*]
(common)
The monitor display and frequency setting of the PU (FR-
DU07/FR-PU04/FR-PU07) can be changed to the motor
speed and machine speed.
To display the machine speed on
, set in [
Pr. 37
] the
machine speed for operation with frequency set in [
Pr. 505
].
For
, set in [
Pr. 37
] the machine
speed at 60Hz operation.
For example, when [
Pr. 505
= 60Hz] and [
Pr. 37
= 1000] on
, 1000 is displayed on the running speed monitor
when the running frequency is 60Hz. When running
frequency is 30Hz, 500 is displayed.
To display the motor speed in
, set the motor
speed at 60Hz operation. The value displayed in monitor is
calculated from the output frequency when slip compensation
is performed during Advanced magnetic vector control in
or when slip compensation is performed in
.
To display the motor speed in
, set the number
of motor poles (one of 2, 4, 6, 8, and 10) or number of motor
poles + 100 (102, 104,106,108, or 110). Under V/F control,
the output frequency of the inverter is displayed in terms of
synchronous speed. Therefore displayed value is a total value
of actual speed and motor slip. This display changes to the
actual speed (estimated value calculated based on the
motor slip) when the Advanced magnetic flux vector control
or Real sensorless vector control is selected on
,
and actual speed from the encoder is displayed when
encoder feed back control or vector control is performed.
When [
Pr. 811
= 1, 11] on
, the setting increments of
speed setting from the PU, speed setting from RS-485
communication or communication options (other than FR-
A7ND, FR-A7NL) and running speed monitor is 0.1r/min.
Note that parameter setting is in 1r/min increments. (For
torque setting increments, refer to page 285.)
When both [
Pr. 37 and Pr. 144
] have been set, their priorities
are as given below.
[
Pr. 144
= 102 to 110] [
Pr. 37
= 1 to 9998] [
Pr. 144
= 2 to 10]
Refer to [
Pr. 52
] when you want to change the PU main
monitor (PU main display). (Refer to page 345)
Since the panel display of the operation panel (FR-DU07)
is 4 digits in length, the monitor value of more than 9999 is
displayed as ----.
When the running speed monitor is selected, each monitor
and setting are determined by the combination of [
Pr. 37
]
and [
Pr. 144
] as the tables on the next page. (Units in the
bold frame are initial values.)
