10.13 : Direction commanded
Adjustment range :F orward (0) or Reverse (1)
Format: 8 bits
This parameter indicates Reverse (1) if the pre-ramp reference
is negative.
It indicates Forward (0) if the pre-ramp reference is positive.
10.14 : Direction running
Adjustment range : Forward (0) or Reverse (1)
Format: 8 bits
This parameter indicates Reverse (1) if the post-ramp reference
is negative.
It indicates Forward (0) if the post-ramp reference is positive.
10.15 : Mains loss
Adjustment range : No (0) or Yes (1)
Format: 8 bits
This parameter indicates Yes (1) during loss of the AC mains
power supply. This parameter is only enabled when parameter
06.03 is not set to No detection (0).
10.16 : DC bus undervoltage
Adjustment range : No (0) or Yes (1)
Format: 8 bits
This parameter indicates Yes (1) when the bus voltage level is
too low.
10.17
: Motor overload alarm
Adjustment range : No (0) or Yes (1)
Format: 8 bits
This parameter indicates Yes (1) when parameter 04.19
«Motor thermal state» becomes greater than 100%.
It indicates No (0) when the value is < 95%.
10.18
: Drive overtemperature alarm
Adjustment range : No (0) or Yes (1)
Format: 8 bits
This parameter indicates Yes (1) when one of the temperatures
displayed for 07.51 to 07.55 exceeds 95% of the max
permitted value.
10.19 : Drive general warning
Adjustment range : Disabled (0) or Enabled (1)
Format: 8 bits
Drive general warning = Yes (1) if 10.12 or 10.17 or 10.18 =
«Yes (1)» or if the Ixt level (
04.21
) exceeds 100%
.
10.20 to 10.29 : Last 10 trips stored
Adjustment range : 0 to 102
Format: 8 bits
Contains the last 10 drive trips.
10.20 : Indicates the most recent trip.
10.29 : Indicates the oldest trip.
The possible trips are:
