Parameter Descriptions
9-19
Maximum Frequency / Decel Time = Decel Rate
Provides the frequency command to the drive when Speed
Reference (P038) is set to 1=Internal Frequency. When enabled,
this parameter will change the frequency command in “real time”
using the integral keypad
keys when in program mode.
Important:
Once the desired command frequency is reached, the
key must be pressed to store this value to
EEPROM memory. If the
key is used before the
key, the frequency will return to the original value
following the normal accel/decel curve.
If Digital Inx Sel (A-051-A054) is set to 16 = MOP Up or 17 = MOP
Down, this parameter acts as the MOP frequency reference.
