∗1 After the power has been shut off, wait at least 10 seconds before turning the power back on.
∗2 To input the CW or CCW signal pulse, wait at least 0.1 second after clearing the ALARM output.
∗3 The turning of END output to "ON" does not necessarily mean the motor has stopped. Provide
enough of a time delay for a halt, which will vary, depending on the acceleration/deceleration rates and
load condition.
The time for END output to turn "ON" after the pulse signal stops will vary, depending on the
pulse-signal input condition and speed-filter setting condition.
∗4 Detect TIM output only at a pulse speed of 500 Hz or less.
No accurate detection is possible at a speed over 500 Hz.
∗5 Turning C.OFF input "ON" shuts off the motor current, at which time the motor loses its holding ability.
It also clears the value on the deviation counter.
