The functions of parameters P1-34, P1-35 and P1-36 are each individual. When
P1-36 is set to 0 (Disabled), the settings of P1-34, P1-35 are still effective. It
indicates that the parameters P1-34 and P1-35 will not become disabled even
when P1-36 is disabled.
Please note:
1. When the source of speed command is analog command, the maximum setting
value of P1-36 is set to 0, the acceleration and deceleration function will be
disabled.

P1 - 38 ZSPD
Default: 100
Applicable Control Mode: ALL
Unit: 0.1 r/min
Range: 0 ~ 2000
Data Size: 16-bit
Display Format: Decimal
Settings:
This parameter is used to set output range of zero speed signal (ZSPD) and
determine when zero speed signal (ZSPD) becomes activated. ZSPD is activated
when the drive senses the motor is equal to or below the Zero Speed Range setting
as defined in parameter P1-38.
