Speed setting by external terminals
(1) Main speed
?Set the main speed as a base, and increase it with the RH signal and decrease it with the RM signal.
The method to set the main speed in each of the operation modes below is as follows.
(2) Acceleration/deceleration operation
The set speed (set by remote setting) and the operating speed change according to the setting of the following
parameters.
(3) Speed setting storage function
The remotely set speed is stored, held, or cleared. When the drive unit is turned ON again and the operation is resumed,
the speed within the parentheses will apply.
Storage conditions
The remotely set speed is stored at the point when the start signal (STF or STR) turns OFF. The remotely set speed is
stored every minute after turning OFF (ON) both of the RH and RM signals. Every minute the latest stored speed value is
compared with the second latest one. When they are not equal, the latest one is written in the EEPROM. The writing in the
EEPROM is not effected by the ON/OFF status of the RL signal.
