Err Cnt; Err (1) To Err (6) - Hitachi SJ700-2 Series Instruction Manual

Chapter 5 Instruction Words
Variable name

ERR CNT

Trip counter
- Explanation
This variable can be used to monitor the number of times the inverter has tripped. The data monitored
with this variable corresponds to the data monitored by the trip counter function (d080). This variable is
read-only.
- Sample program: Program to check whether the inverter has tripped more than 10,000 times

Variable name
ERR (1) to
Trip monitoring 1
ERR (6)
to 6
- Explanation
These variables can be used to monitor the causes of the last six trips made by the inverter. The data
monitored with this variable corresponds to the data monitored by trip monitoring functions 1 to 6 (d081
to d086). These variables are read-only.
- Sample program: Program to check whether the last six trips include one caused by overcurrent

latest.
MATCH : Check the factor of the trip five trips before the
latest.
