MN715J Programming and Operation 4-13
Parameter Block Definitions Level 1
PRESET SPEEDS
Preset Speeds #1 – #7 Allows selection of 7 predefined motor operating speeds. Each
speed may be selected using external switches connected to the control terminal strip
(J4). For motor operation, a motor direction command must be given along with a preset
speed command (at J4).
ACCEL/DECEL RATE
Accel Time #1,2 Accel time is the number of seconds required for the control to
increase the output frequency from the “Min Output Frequency” to the frequency
specified in the “Max Output Frequency” parameter in the Level 2 Output Limits
block.
Decel Time #1,2 Decel time is the number of seconds required for the control to
decrease the output frequency from the frequency specified in the “Max Output
frequency” parameter to the “Min Output Frequency”.
S-Curve #1,2 S-Curve is a percentage of the total Accel or Decel time. It is
non-linear to provides smooth starts and stops. Figure 4-2 illustrates how motor
acceleration and deceleration is changed using a 40% S-Curve. 0% represents
no “S” and 100% represents full “S” with no linear segment.

Example: Maximum Output frequency =100 Hz; Preset frequency = 50 Hz,
Accel Time=10 Sec. In this example, control output frequency will be 50Hz, 5
seconds after commanded from minimum output frequency.
Note: Accel #1, Decel #1 and S-Curve #1 are associated together. Likewise, Accel
#2, Decel #2 and S-Curve #2 are associated together. These associations
can be used to control any preset speed or external speed command (Pot).
Note: Since the motor design uses rotor slip to produce torque, the motor speed will
not necessarily increase/decrease in a linear manner with motor frequency.
Note: If faults (motor trips) occur during rapid Accel or Decel, selecting an S-curve
may eliminate the faults without affecting the overall ramp time. Some
adjustment of Accel, Decel and S-Curve settings may be necessary to
optimize your application.
JOG SETTINGS
Jog Speed Jog Speed is the commanded frequency used during jog. Jog speed can
be initiated from the keypad or terminal strip. At the keypad, first press the JOG
key then either the FWD or REV key.
Jog Accel Time is the Accel Time used during jog.
Jog Decel Time is the Decel Time used during jog.
Jog S-Curve is the S-Curve used during jog.
