CSD Series Variable Frequency AC Drive
MOTORTRONICS
- 35 -
Fn17 - Fn23 = 0 - 400 Hz: Multispeed 1 - 7
Fn17 - Fn23 are seven preset speed settings. When Fn56 - 58 changes
from 0 to 2, the switches connected to TM2 pins 6 - 8 can control the
speed of the drive. Note: For Fn56 - 58, entering 00-15 provides normally
open (N.O.) contacts and 16-31 provides normally closed (N.C.)
contacts.

Two timer functions can be used to control speeds for Fn17 - 23. In the
first timer function, if Fn84 = XXX1 and Fn56 - 58 = 0 - 2, or 16 - 18,
then this changes the multifunction input switches from preset speed
contacts to timer input contacts. A pulse signal is received on the
multifunction input, the drive will run at the time specified by Fn85 -
Fn91 at the frequency specified by Fn17 - Fn23. After the time has
elapsed, the drive will return to the frequency set by keypad or external
analog signal input depending on the programming of Fn11. (See Figure
5 - 5c .)
On the second timer function, if Fn84 = XXX1 and Fn56 - Fn58 = 14 or
30, this changes the multifunction input to an automatic cycle
initialization contact. When the contact is momentarily made on TM2,
the drive will go to the speed of Fn17 for time of Fn85, then will go to
the speed of Fn18 for time of Fn86. This continues through the seven
preset speeds of Fn17 - 23 for the seven preset times of Fn85 - 91.
After the timed cycle has elapsed, the drive will return to the frequency
set by keypad or external analog signal input depending on the
programming of Fn11. (See Figure 5 - 5d.)
Note: A new speed setting or timer setting cannot be inserted into an
ongoing timer and speed function. The priority of the preset speed
signals is as follows: Jog >>Multiple Speed>>Digital operator. The
jog contact has the highest priority and the digital operator has the
lowest priority.
