7.7 VSD Object Configuration Properties (CPs)
This section details VSD object configuration properties (CPs) that need supplemental descriptions. For CPs not
found in this section, refer to Section 7.3 "VSD Object."
(1) SCPT_maxRcvTime
Receive heartbeat. This CP specifies the heartbeat receive interval for input NVs listed in Table 7-11 in
block. If no data is received within this interval after the reception of the last data, the interface card
interprets the state as a LONWORKS communications error.
Setting the heartbeat time at 0.0 s does not break the connection to the LONWORKS network even if no
data is received.
For details about the settings and activities on a LONWORKS connection break, refer to Chapter 8,
Section 8.1 "Specifying an Inverter Reaction to LONWORKS Communications Errors."
- Data setting range: 0.0 to 6553.4 s (0.1 s resolution)
- Default setting: 0.0 s (Ignore connection break)
Writing a value (e.g., 6553.5) exceeding the data setting range to this CP displays the value but
does not update the internal value, retaining the previously written data.

(2) SCPT_maxSendTime
Send heartbeat. This CP specifies the constant updating period for all output NVs listed in Table 7-12 below
in block. Specifying it periodically updates those NVs that include the internal monitor values.
Setting the send heartbeat at 0.0 s does not cause updating.
- Data setting range: 0.0 to 6553.4 s (0.1 s resolution)
- Default setting: 0.0 s (No periodic updating)
