Hard Wire Base Block Function While the Servo Is OFF
(1) Checking the Status of the Hard Wire Base Block
No alarm will occur when a SERVOPACK enters the hard wire base block state. Therefore, you must use the
following method to manually monitor the hard wire base block state.
• Constantly monitor to see if SVCMD_IO.ESTP (bit 7) changes from 0 to 1.
• Check to see if SVCMD_STAT.M_RDY (bit 12) changes from 1 to 0 and SVCMD_STAT.SV_ON (bit 13)
changes from 1 to 0.
(2) Hard Wire Base Block Procedures
Hard Wire Base Block Function While the Servo Is OFF
The host controller sends the SMON (30 hex) command and waits for the SERVOPACK to leave the hard wire
base block state.
When Hard Wire Base Block Occurs While the Servo Is ON
The motor stops according to the setting of parameter Pn001.0.
From the host controller, send the SV_OFF command followed by the SMON (30 hex) command. Then, the
host controller must wait until the hard wire base block is cleared.
Note: If the hard wire base block state is entered during execution of any of the following commands, a command warning
will occur. The command warning is reset automatically when the correct command is received by the SERVO-
PACK. In this case, the warning is automatically reset when the SV_OFF (32 hex) command or any other command
not listed below (e.g., the SMON (30 hex) command) is received.
• SV_ON
• INTERPOLATE
• POSING
• FEED
