Preset Speed 13
Program
Frequency
Preset Speeds
This parameter assigns an output frequency to binary number 1101 and is
identified as Preset Speed 13. The binary number is applied to I1 – I4 of the
ACE G9-120V-PCB to output the Preset Speed (see
F018
for additional
information on this parameter).
Direct Access Number — F292

Factory Default — 0.00
Changeable During Run — Yes
Minimum — Lower Limit (

Preset Speed 14/Lower-Limit Slow Speed
Program
Frequency
Preset Speeds
This is a dual-function parameter. The two functions are described below.
1) This parameter assigns an output frequency to binary number 1110 and is
identified as Preset Speed 14. The binary number is applied to I1 – I4 of the
ACE G9-120V-PCB to output the Preset Speed (see
F018
for additional
information on this parameter).
2) The Lower-Limit speed and Deceleration time settings are changed once
the crane approaches the end of its range (hoist or traverse). Upon
approaching the end-of-range, as detected by the closure of the Lower-Limit
Slow-Speed Limit-Switch, the implementation of the modified Lower-
Limit Slow Speed (
F293
) and
Deceleration Time At Slow-Speed Limit-
Switch DOWN
(
F285
) settings take effect.
Direct Access Number — F293
Parameter Type — Numerical
Factory Default — 6.00
Changeable During Run — Yes
Minimum — Lower Limit (

Preset Speed 15/Upper-Limit Slow Speed
Program
Frequency
Preset Speeds
This is a dual-function parameter. The two functions are described below.
1) This parameter assigns an output frequency to binary number 1111 and is
identified as Preset Speed 15. The binary number is applied to I1 – I4 of the
ACE G9-120V-PCB to output the Preset Speed (see
F018
for additional
information on this parameter).
2) The Upper-Limit speed and Deceleration time settings are changed once
the crane approaches the end of its range (hoist or traverse). Upon
approaching the end-of-range, as detected by the closure of the Upper-Limit
Slow-Speed Limit-Switch, the implementation of the modified Upper-
Limit Slow Speed (
F294
) and
Deceleration Time at Slow-Speed-Limit UP
(
F283
) settings take effect.
Direct Access Number — F294
Parameter Type — Numerical
Factory Default — 6.00
Changeable During Run — Yes
Minimum — Lower Limit (

Maximum — Upper Limit (
F012

Units — Hz
PWM Carrier Frequency
Program
Special
Carrier Frequency
This parameter sets the frequency of the Pulse Width Modulation (PWM) signal
applied to the motor.
Note:
When operating in the Vector Control mode the carrier
frequency should be set to 2.2 kHz or above
.
Note:
If the PWM carrier frequency is set at 2.0 kHz or above, it cannot
be decreased below 2.0 kHz while running. If the PWM carrier
frequency is set at 1.9 kHz or below, it cannot be increased above
2.0 kHz while running. Either change requires that the ASD be
stopped and restarted for the changes to take effect.
