Speed setting by external terminals
4
PARAMETERS
(1) Remote setting function
Use Pr. 59 to select whether the remote setting function is used or not and whether the speed setting storage function in
the remote setting mode is used or not.
When Pr. 59 is set to any of "1 to 3" (remote setting function valid), the functions of the RH, RM and RL signals are
changed to acceleration (RH), deceleration (RM) and clear (RL).
When using the remote setting function, following speeds can be compensated to the speed set by RH and RM operation
according to the operation mode.
During External operation (including
Pr. 79
= "4") ................................. external
speed
command other than multi-speed
settings
During External operation and PU combined operation (
Pr. 79
= "3").... PU
speed
command or terminal 4 input
During PU operation .............................................................................. PU speed command
(2) Speed setting storage
The speed setting storage function stores the remotely-set speed (speed set by RH/RM operation) into the memory
(EEPROM). When power is switched OFF once, then ON, operation is resumed with that rotation speed value. (Pr. 59 = 1)
<Speed setting storage conditions>
Speed at the point when the start signal (STF or STR) turns OFF
Remotely-set speed is stored every minute after turning OFF (ON) the RH (acceleration) and RM(deceleration)
signals together. (The speed is overwritten if the latest speed is different from the previous speed when comparing
the two. The state of the RL signal does not affect writing.)
NOTE
The range of speed changeable by RH
(acceleration) and RM (deceleration) is 0 to
maximum speed (Pr. 1 or Pr. 18 setting). Note
that the maximum value of set speed is (main
speed + maximum speed).
When the acceleration or deceleration signal switches ON, acceleration/deceleration time is as set in Pr. 44 Second
acceleration/deceleration time and Pr. 45 Second deceleration time. Note that when the time set in Pr. 7 or Pr. 8 is longer than
the time set in Pr. 44 or Pr. 45, the acceleration/deceleration time is as set in Pr. 7 or Pr. 8. (when RT signal is OFF)
When the RT signal is ON, acceleration/deceleration is made in the time set in Pr. 44 and Pr. 45, regardless of the Pr. 7
or Pr. 8 setting.
Even if the start signal (STF or STR) is OFF, turning ON the acceleration (RH) or deceleration (RM) signal varies the
preset speed. (When Pr. 59 = "1" or "2")
When switching the start signal from ON to OFF, or changing speed by the RH or RM signal frequently, set the speed
setting value storage function (write to EEPROM) invalid (Pr. 59 = "2, 3"). If set valid (Pr. 59 = "1"), speed is written to
EEPROM speed, this will shorten the life of the EEPROM.
Changing the terminal assignment using Pr. 178 to Pr. 182 (input terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
