P2 - 38 GBIT

Special Function

Default: 0
Applicable Control Mode: P/S/T
Unit: N/A
Range: 0H ~ FFFFH
Settings:
0 0
Bit0 ~ Bit9 and Bit11 ~ Bit15: Reserved. Must be set to 0.
Bit10: DI ZCLAMP function selection (The users should set Bit10 to 400H directly.)
When the following conditions are all met, ZCLAMP function will be activated.
Condition1: Speed mode
Condition2: DI ZCLAMP is activated.
Condition3: External analog speed command or internal registers speed command is less than
parameter P1-38.
Bit10 = 0: Locked at the position when ZCLAMP conditions are satisfied.
Bit10 = 1: Speed command is forced to 0 RPM when ZCLAMP conditions are satisfied.
How to select these two functions?
If the users want to use the edge of a D1 signal to stop the motor at the desired position and do
not care the speed deceleration curve, then set Bit10 of P2-38 to 0.
If the users want to eliminate the analog voltage offset to stop the motor at low voltage and they
want to keep the acceleration and deceleration speed curve, then set Bit10 of P2-38 to 1.
