Magnitude Of Speed Change Setting (Pr.295) - Mitsubishi Electric FR-E700EX Instruction Manual

4.21.3 Magnitude of speed change setting (Pr.295)

Setting this parameter increases the magnitude of speed which changes according to the rotated amount of the setting
dial, improving operability.

setting
The above parameter can be set when Pr.160 Extended function display selection = "0". (Refer to page 182)

The above parameter allows its setting to be changed during operation in any operation mode even if "0" (initial value) is set in Pr.77 Parameter write selection

Valid when the frequency increments or machine speed increments is selected with Pr.37 or Pr.144. (Refer to page 153)
(1) Basic operation
When a value other than "0" is set in Pr.295, the minimum varying width when the set speed is changed by the setting dial can
be set.
For example, when "10" is set in Pr.295, one click (one dial gauge) of the setting dial changes the speed in increments of 10r/
min20r/min30r/min.
When Pr. 295 = "1"
1 click
 One rotation of the setting dial equals to 24 clicks (24 dial gauges).
REMARKS
 When machine speed display is selected with Pr.37, the minimum increments of the magnitude of change is determined by
Pr.295 as well. Note that the setting value may differ as speed setting changes the set machine speed and converts it to the
speed display again.
 When the set frequency is 100 or more, frequency is displayed in 0.1 increments. Therefore, the minimum varying width is 0.1
even when Pr.295 < 0.1.
 When the machine speed setting is 1000 or more, frequency is displayed in 1 increments. Therefore, the minimum varying
width is 1 even when Pr.295 < 1.
NOTE
 For Pr.295 , unit is not displayed .
 This parameter is valid only in the set speed mode. When other speed-related parameters are set, it is not activated.
 While the frequency setting is being selected, setting "10" changes the frequency setting in 10Hz increments. Be
cautions of the excess speed (in potentiometer mode).
