Speed Control Mode - Mitsubishi Electric GENERAL PURPOSE AC SERVO MR-E- A/AG Instruction Manual

5. PARAMETERS
Class No. Symbol
Function selection 2
20 *OP2
Used to select restart after instantaneous power failure,
servo lock at a stop in internal speed control mode, and slight
vibration suppression control.
21 *OP3 Function selection 3 (Command pulse selection)
Used to select the input form of the pulse train input signal.
(Refer to Section 3.4.1.)
Name and function
Restart after instantaneous
power failure
If the input power supply voltage
had reduced in the internal speed
control mode to stop the servo motor
due to the undervoltage alarm (AL.10)
but the supply voltage has return-
ed to normal, the servo motor can
be restarted by merely switching
on the start signal without resett-
ing the alarm.

0: Valid
1: Invalid
Slight vibration suppression control
Made valid when auto tuning selection is
set to "0400" in parameter No. 2.
Used to suppress vibration at a stop.
0: Invalid
1: Valid
In case of the internal speed control mode,
set "1" at the second digit and validate servo
lock at stop to use this setting.
