Signal supervision. The drive monitors whether certain user selectable
variables are within the user-defined limits. The user may set limits for speed,
current etc. Supervision status can be monitored with relay output. See
parameter group 14 RELAY OUTPUTS.
Selects the first supervised signal. Supervision limits are defined by
parameters 3202 SUPERV 1 LIM LO and 3203 SUPERV 1 LIM HI.
Example 1: If 3202 SUPERV 1 LIM LO < 3203 SUPERV 1 LIM HI
Case A = 1401 RELAY OUTPUT 1 value is set to SUPRV 1 OVER. Relay
energizes when value of the signal selected with 3201 SUPERV 1 PARAM
exceeds the supervision limit defined by 3203 SUPERV 1 LIM HI. The relay
remains active until the supervised value drops below the low limit defined by
3202 SUPERV 1 LIM LO.
Case B = 1401 RELAY OUTPUT 1 value is set to SUPRV 1 UNDER. Relay
energizes when value of the signal selected with 3201 SUPERV 1 PARAM
drops below the supervision limit defined by 3202 SUPERV 1 LIM LO. The
relay remains active until the supervised value rises above the high limit
defined by 3203 SUPERV 1 LIM HI.

Example 2: If 3202 SUPERV 1 LIM LO > 3203 SUPERV 1 LIM HI
The lower limit 3203 SUPERV 1 LIM HI remains active until the supervised
signal exceeds the higher limit 3202 SUPERV 1 LIM LO, making it the active
limit. The new limit remains active until the supervised signal drops below the
lower limit 3203 SUPERV 1 LIM HI, making it the active limit.
Case A = 1401 RELAY OUTPUT 1 value is set to SUPRV 1 OVER. Relay is
energized whenever the supervised signal exceeds the active limit.
Case B = 1401 RELAY OUTPUT 1 value is set to SUPRV 1 UNDER. Relay is
de-energized whenever the supervised signal drops below the active limit.
