NOTE
If the reference source is disabled, the torque limit results from the max. absolute torque
determined by the drive size and the motor size.
The max. absolute torque is the max. value ranging between the absolute values of C047
and C048 (motor 1, and relevant parameters for motor 2 and motor 3).
Max. absolute torque = Max( | C047 | , | C048 |)
Factory-setting : the reference source is disabled (C147=0), so the torque limit depends on the max. absolute torque
(see also the INPUTS FOR REFERENCES MENU).

Function
The drive factory-setting (0: StandBy or Fluxing) allows switching over from Remote
to Local mode (and vice versa) only when the drive is not running.
Different settings allowed by parameter C148
are detailed below; switching from
Remote to Local mode (and vice versa) can be performed even when the drive is
running:
• No Bumpless → When switching from Remote to Local mode, a “zero”[*]
speed or torque reference is sent to the drive; the START
button must be pressed
to start the drive.
• Commands Bumpless →
When switching from Remote to Local mode, a
“zero”[*] speed or
torque reference is sent to the drive, but the running conditions
are the same as in Remote mode. For example, if the motor is running in Remote
mode, the drive still runs even in Local mode and the reference can be changed
with the INC/DEC key, starting from “zero”.
• All Bumpless → When
switching from Remote to Local mode, the drive
maintains the same speed/torque reference and the same running condition as in
Remote mode. For example, if the motor is running at 1000 rpm in Remote mode,
the drive still ru
ns even in Local mode with a reference of 1000 rpm that can be
changed with the INC/DEC key, starting from “zero”.
[*] Or to the smallest value compatible with C028/C029 or C047/C048.
NOTE
Parameter C148 affects parameters C140 to C147 and C285 to C287 (see PID
CONFIGURATION MENU) when the PID controller is enabled.
