Chapter 8 Servo Parameters
Revision January 2011 8-65
Settings:
Used to set the period of time between when the servo drive is Off (Servo Off) and when
electromagnetic brake output signal (BRKR) is inactivated.
Please note:
1. When servo is commanded off and the off delay time set by P1-43 has not elapsed,
if the motor speed is lower than the setting value of P1-38, the electromagnetic
brake will be engaged regardless of the off delay time set by P1-43.
2. When servo is commanded off and the off delay time set by P1-43 has elapsed, if
the motor speed is higher than the setting value of P1-38, electromagnetic brake
will be engaged regardless of the current motor speed.
3. When the servo drive is disabled (Servo Off) due to a fault (except AL022) or by
EMGS (Emergency stop)) being activated, if the off delay time set by P1-43 is a
negative value, it will not affect the operation of the motor. A negative value of the
off delay time is equivalent to one with a zero value.

Settings:
This parameter is used to set the numerator of the electronic gear ratio. The
denominator of the electronic gear ratio is set by P1-45. P2-60 ~ P2-62 are used to set
the additional numberators.
Please note:
1.
In PT mode, the setting value of P1-44 can be changed only when the servo drive is
enabled (Servo On).
2.
In PR mode, the setting value of P1-44 can be changed only when the servo drive is
disabled (Servo Off).
