Inverter Operation Monitoring Instruction - Hitachi NT2021XA Instruction Manual

Chapter 2 Syntax

Inverter operation monitoring instruction

- Format
<variable 1> = <output terminal function>
- Explanation
This instruction fetches the on / off status of the inverter output terminal specified by
in <variable 1>. When the specified output terminal is off, the value of
1> is "1".
The function and operation of the specified output terminal are the same as those that can be specified by the terminal function
(SJ700 /L700/SJ700B: C021 to C026 / WJ200 : C021, C022, and C026) on the inverter. For details, refer to the Inverter
Instruction Manual.

is "0"; when it is on, the value of
: Set the output frequency to 60 Hz.
: Set the acceleration time to 10 seconds.
: Set the deceleration time to 10 seconds.
: Wait until X (01) is turned on.
: Increase the acceleration time to 30
seconds.
: Wait until the output frequency reaches
the set frequency.
: Wait until X (02) is turned on.
: Reduce the set frequency to 5 Hz.
: Increase the deceleration time to 30
seconds when ZS is on.
: Operate the motor at 5 Hz for 10
seconds.
: Decelerate and stop the motor.
