7.2 Maximum Speed (MAX):
Sets the maximum speed
of the motor.
1. Catalog Nos. ID5202-CO, ID5203-CO:
The
MAX Trimpot is factory set to 100% of frequency
setting. For a higher maximum speed setting,
rotate the MAX Trimpot clockwise. For a lower
maximum speed setting, rotate the MAX Trimpot
counterclockwise. See Figure 27.
2. Models ID5401-CO, ID5402-CO, ID5403-CO,
ID5405-CO:
The MAX Trimpot on the ID5SI-1 is
a 10-turn trimpot which allows for accurate setting of
the maximum speed of the motor. The MAX trimpot is
factory set to 100% of frequency setting. For a higher
maximum speed setting, rotate the MAX Trimpot
clockwise. For a lower maximum speed setting, rotate
the MAX Trimpot counterclockwise. See Figure 28.
7.3 Acceleration (ACC):
Sets the amount of time for the motor
to accelerate from zero speed to full speed. The ACC
Trimpot is factory set to 1.5 seconds. For longer
acceleration time, rotate the ACC Trimpot clockwise.
For more rapid acceleration, rotate the ACC Trimpot
counterclockwise. See Figure 29.
Note:
Rapid acceleration settings may cause the cur-
rent limit circuit to activate, which will extend the
acceleration time
.
7.4 Deceleration (DEC/B):
Sets the amount of time for
the motor to decelerate from full speed to zero
speed. The DEC/B Trimpot is factory set to 1.5 sec-
onds. For longer deceleration time, rotate the DEC/B
Trimpot clockwise. For more rapid deceleration,
rotate the DEC/B Trimpot counterclockwise.
See Figure 30.
Application Note:
On applications with high inertial
loads, the deceleration may automatically increase in
time. This will slow down the rate of speed of
decrease to prevent the bus voltage from rising to the
Overvoltage Trip point. This function is called
Regeneration Protection. It is recommended that for
very high inertial loads that both the ACC and DEC/B
Trimpots should be set to greater than 10 seconds.
7.5 Slip Compensation (COMP):
Sets the amount of Volts/Hz to maintain set motor speed
under varying loads. The COMP Trimpot is factory set to 1.5 Volts/Hz, which provides
excellent speed regulation for most motors. To increase the slip compensation, rotate the
COMP Trimpot clockwise. To decrease the slip compensation, rotate the COMP Trimpot
counterclockwise. See Figure 31, on page 24.
