Mitsubishi Electric FR-A820-00046 (0.4K) Instruction Manual page 339

NOTE
• When a plug-in option in installed on the inverter, the option parameters can also be read.
• Every parameter can be read regardless of the Pr.160 setting when reading parameters via a communication option.
• When reading the parameters using the RS-485 terminals, all parameters can be read regardless of the Pr.160 setting by
setting Pr.550 NET mode operation command source selection and Pr.551 PU mode operation command source
selection.

3 (USB)
9999 (Automatic determination)
(initial value)
• When the LCD operation panel (FR-LU08) or the parameter unit (FR-PU07) is installed, Pr.15 Jog frequency, Pr.16 Jog
acceleration/deceleration time, C42(Pr.934) PID display bias coefficient, C43(Pr.934) PID display bias analog value,
C44(Pr.935) PID display gain coefficient, C45(Pr.935) PID display gain analog value and Pr.991 PU contrast adjustment
are displayed as simple mode parameters.
 User group function (Pr.160, Pr.172 to Pr.174)
• The user group function is a function for displaying only the parameters required for a setting.
• A maximum of 16 parameters from any of the parameters can be registered in a user group. When Pr.160 = "1", reading/
writing is enabled only for the parameters registered in user groups. (Parameters not registered in user groups can no
longer be read.)
• To register a parameter in a user group, set the parameter number in Pr.173.
• To clear a parameter from a user group, set the parameter number in Pr.174. To batch clear all the registered parameters,
set Pr.172 = "9999".
 Registering a parameter in a user group (Pr.173)
• To register Pr.3 in a user group
