Hitachi SJ7002 Series Instruction Manual page 157

If intelligent terminal [PCLR] is assigned, when it is ON the current position counter is cleared
and the position deviation counter is also cleared.
When the inverter is in Absolute Position Control Mode, some functions are necessarily
disabled:
• Intelligent terminal [ATR] is ignored (because torque control is disabled)
• Intelligent terminal [STAT] is ignored (because pulse train position control is disabled)
• Home search function is disabled
Teaching
The teaching function allows you to make the inverter run and stop the motor as desired and
store current position data to a position command memory location that you select. Assign the
Function
[ORT] Orientation function (option code 45) to an intelligent input. The [ORT] terminal
functions as the teaching input terminal when P012 Control Pulse Setting is set to 02 (Absolute
Position Control) or 03 (High-resolution Absolute Position Control).
The teaching procedure is as follows:
1. Select the teaching position memory location by setting P074.
2. Move the work piece or machine to the desired location. Enter an operation command while
Teaching operation can be performed when power is input to the power supply terminals [R0]
and [T0] of the inverter control circuit. The current position counter also operates when an
external device moves the work piece. Therefore, the teaching operation can also be performed
when the inverter does not operate (move) the machine.
NOTE: When teaching position data to an inverter that is not operating the machine, be sure to
either disconnect input power terminals ([R], [S], and [T]) or disconnect the motor output
terminals ([U], [V], and [W]). Otherwise, personal injury or damage to equipment may result.
3. Press the STR key on the digital operator when the target position is reached.
4. The current position data is stored to the memory area selected by parameter P074 teaching
the [ORT] terminal is in the ON state. The speed and accel/decel settings selected at the
operation command input are applied.
