3-1 Driver Specifications
Sensor ON Input (SEN)
Pin 20: Sensor ON input (SEN)
Pin 13: Signal ground (SENGND)
Function
This input changes to enable (set value: 1) according to the setting of Absolute Interface
Function Selection (Pn616).
When the SEN signal turns ON, this performs serial transmission of multi-rotation data of the
absolute encoder and also outputs 1-rotation data as the initial incremental pulses.
If the SEN signal is OFF, motor power supply is not possible even when the RUN signal
(Operation command) is input. The RUN signal changes to enable after the SEN signal turns
ON and the normal operation of encoder becomes ready.
3
Backup Battery Input (BAT)
Pin 42: Backup battery +input (BAT)
Pin 43: Backup battery −input (BATGND)
Function
Backup battery connection terminals when the absolute encoder power is interrupted.
Normally do not connect anything to this terminal, because a battery is connected to the battery
holder for absolute encoder battery cable. (Never connect to both. Failure may result.)
Speed Command Input (REF), Torque Command Input (TREF1) and Speed Limit Input (VLIM)
Pin 14: Speed command input (REF), torque command Input (TREF1) and speed limit input
(VLIM)
Pin 15: Analog input ground (AGND1)
Function
During speed control
Speed command is input. Use the Speed Command Scale (Pn302) to change the rotation speed
scale for the command input.
During torque control
This signal provides either a torque command input (set value: 0 or 2) or speed limit input (set
value: 1) according to the setting of Torque Command/Speed Limit Selection (Pn317).
In the case of torque command input 1 (TREF1), you can use Torque Command Scale (Pn319)
to change the rotation speed scale relative to the command input.
In the case of speed limit input (VLIM), you can use the Speed Command Scale (Pn302) to
change the limit speed scale relative to the analog input.
