MINIMUM SPEED (P.003)
Selects the minimum speed of the drive without being stopped. It is typically greater than zero.
If it is less than 10% of MAXIMUM SPEED, an alarm is generated.
Parameter Range: 0 to MAXIMUM SPEED (RPM or user-defined units)
Default Setting: 0 (RPM or user-defined units)
Parameter Type: Tuneable
OIM Menu Path(s): Drive Reference - Drive Reference Limits, Quick Start
DANGER
This drive can operate at and maintain zero speed when this parameter is set to on. The user is
responsible for assuring safe conditions for operating personnel by providing suitable guards, audible
or visual alarms, or other devices to indicate that the drive is operating at or near zero speed. Failure
to observe this precaution could result in severe bodily injury or loss of life.
MOP ACCEL TIME (P.115)
Only available if the I/O Expansion kit is installed.
Time in which the motor operated potentiometer (MOP) output can change from zero to TOP SPEED.
The MOP function provides a manual reference to the speed/voltage loop when CONTROL SOURCE
SELECT is set to TERMBLK and the MANUAL REF SELECT is set to MOP.
Parameter Range: ACCELERATION TIME to 300.0 seconds
Default Setting: 5.0 seconds
Parameter Type: Tuneable
OIM Menu Path(s): Drive Reference - Drive Reference Ramp
Refer also to Parameters: ACCELERATION TIME (P.001), CONTROL SOURCE SELECT (P.000),
DECELERATION TIME (P.002), MANUAL REF SELECT (P.106),
MAXIMUM SPEED (P.004), MINIMUM SPEED (P.003),
MOP DECEL TIME (P.120), MOP OUTPUT (P.191),
MOP RESET ENABLE (P.116), TOP SPEED (P.011)
The MOP OUTPUT is increased through digital input 4 (terminal 63) and decreased through digital input
3 (terminal 62) on the I/O Expansion board. The MOP OUTPUT is limited to prevent going over
MAXIMUM SPEED or under MINIMUM SPEED.
MOP ACCEL TIME and MOP DECEL TIME set the time in which the MOP OUTPUT can change from
zero to TOP SPEED and vice versa. To prevent the S-curve block from limiting the rate of change from
the MOP OUTPUT, MOP ACCEL TIME has a low limit equal to ACCELERATION TIME. MOP DECEL
TIME has a low limit equal to DECELERATION TIME.
When MOP RESET ENABLE is ON, the MOP output goes to MINIMUM SPEED when the drive stops. If
it is OFF, the MOP OUTPUT remains at its present level when the drive stops. MOP RESET ENABLE
affects the operation of OIM reference, even if the I/O Expansion kit is not installed.
