Communication command2

 (Communication Number : FA20, FA22)

This command is enabled only when the communication command is enabled.    Set Bit 15 of Com-
munication Command 1 (communication Number: FA00, FA04) to “1” (enable).    When enabling the
communication command by Communication Command 1, commands by communication can be
given

 

the priority irrespective of the setting of the command mode selection parameter ().

However, if “48 (49): Forced switching from communication to local,” “56 (57): Forced continuous
operation,” or “58 (59): Specified speed operationj” is set by input terminal function selection
( to ), the enabled command and frequency will be given the priority.

Once enabled, this setting will be enabled till disable is set (0 setting), power is turned off or is reset,
or factory default setting () is selected.

Note: The acceleration/deceleration change command ORs with Bit 6 of Communication number

FA00 and FA04.

Set Bit 6 of FA00 and FA04 to “0” and use FA20 and FA22 when changing acceleration/deceleration
in four types.  Acceleration/deceleration 4 will be set when both Bit 8 of Communication number
FA20 and FA22 (or Bit 6 of Communication number FA00 and FA04) and Bit 9 of Communication
number FA20 and FA22 are set.
